I've heard, for about 20 years now, that a development just around the corner will make laptops last a week without a charge. Never happens. Color me skeptic.

"Imagine your phone lasting for days" Why yes, I do remember the 3310

When I was young...we used graphite rods encased in wood to do calculations on flat sheets of wood pulp.

Back in 2003 when I was studying Computer Science at FSU, one of the breakthroughs the university had was regarding graphene. I'm still waiting for it to materialize into ANYTHING we use daily or get a benefit out of.

It's intriguing how often I stumble upon a seemingly groundbreaking technology, only to discover it's been around since the mid-20th century.

10 years ago: "We gonna have graphene computers!" 10 years from now: "We gonna have graphene computers!"

Graphene is just like Nuclear fusion, always 10 years away 😅

Graphene breakthroughs seem to happen just often enough that makes me believe I'll never live long enough to see any graphene products.

The year is 2120... We will finally have graphene computers in 10 years!

This is the same case as with batteries, every year you hear about some breakthrough tech and still your phone dies in a day with the same old lithium battery.

Clicked the video, 40sec in: "Graphene". Rolled my eyes so hard I had to look for them on the carpet.

At <a href="#" class="seekto" data-time="481">8:01</a> you say "deficit free" when the text reads "defect free." The distinction between those two words is VERY important when it comes to semiconductor chips, as wafer defects are a huge deal in the production of semiconductor processing chips.

But when will we achieve cold fusion?

Those chips will run ads faster.

Wow amazing! Thank you for covering this!

Hats off for making this as accessible as possible!

A little thing about graphene synthesis. There is a company out of San Diego called Grolltex which has made strides in synthesis and fabrication. Their CEO did his PhD thesis on the subject, too. The main bottleneck is not necessarily the synthesis of pristine graphene, but transferring and fabricating on different surfaces. That's what this company is trying to do. I know the sad joke about graphene being able to do anything except leave the lab, but the number of companies that are working on scaling, the number of companies working on graphene fabrication infrastructure, and also the very smart people in materials synthesis labs have put out lots of papers recently on the subject. There is one professor at Johns Hopkins who is working on graphene synthesis via CO2 splitting, which is exciting. If you're an aspiring materials scientist or chemist, this is a great field to be in right now.

There's 9 Tech Readiness Levels, and a working graphene transistor is TRL 3. They still have a looooong ways to go.

Thanks you for your clear, interesting updates on the latest research. You are amazing!

You mentioned the 'band gap'. Very key with this tech idea to be resolved first before it can/will be rolled out. loved the video mate.

Graphene based chips? This has been speculated on and teased for many, many years. I’ll believe it when I see it

Very impressive but the most important info is missing: How did they achieve the "semiconductiveness" for graphine? What is going on in detail so the meterial behaves that way?

I don't know where you got your intro music (you are watching Cold Fusion) and it just really hits the right things. Hard to describe but I really love it so well done! Also I do enjoy your voice and coverage of topics - I do really look forward to your next videos.

I'm an ingeneer specialized in powerelectronics. We are working since around 2019 with SiC Mosfets. here are some conclusions in comparison with standard IGBT Moduls (although I obviosly can only talk about powerelectronic side, not microelectronics) - If they die (explode) they do so pretty quite, that's nice. They also don't push the silicon everywhere. I tell you, cleaning a cabinet where a IGBT did explode is annoying... - They are faster. witch IGBTs our switchingfrequency was at (depending on the output current) 2...10 kHz, with SiC we are usually at 12...20 kHz with comparable current. That reduces the losses in the chokes significantly, and reduces the noice by far. Sadly it seems, that the chokes are now at their limit. even if the output current of the Semiconductors could be increased, there are no chokes to smoothe the current out. with 25 kHz most choke technologies are also already at the optimum with copper and iron losses. - They survive overvoltages longer/easier. - they get extreamly hot, therefore the chip is a lot closer to the baseplate (wich is attached to a heat sink. sadly this increases the parasitic capasity, and because of that also EMC noise against PE. It easily interferes with other devices. An EMC Filter is mostly required. - because of the higher switching frequency parasitic problems have gone up a notch as well. For example: we build a bidirectional, galvanically isolated DC//DC converter. In the lab it worked with 30 kHz, but when we build it in a cabinet, we had to reduce the switching frequency to 17 kHz, just because the cables were a few centimeters longer, and therefore the parasitic inductance inceased. The difference is, again, the lab compared to a real application. - they are, at least for now, still very expansive All in all, it is nice, yes, but it is not the all mighty solution. All the manufacturers have already quited down significantly about innovations.

Most peaceful videos to listen to , thank you

@<a href="#" class="seekto" data-time="292">4:52</a> that's the first time I've ever heard of conductivity explained like that. thank you

Finally, this channel talks about the news about the graphene semiconductor that came out almost 4 months ago. Brilliant. :)

I love this hopeful video! Thanks so much for enlightening me! ❤

The name of the channel goes well with the content beautifully haha

I love episodes like this. It gets me interested and enthusiastically excited for the future like I was in my 20s again. Thanks.

Incogni man! we need more of that.

Thanks for making this video, Dagogo!!

<a href="#" class="seekto" data-time="45">0:45</a> didn't know Einstein is still alive!!

This idea is decades old

Having done my PhD research on graphene, this research really gets me hyped up for the future

ColdFusion's technical videos are my favourite

Watches for the content, falls asleep due to voice and music 🎶 ❤

A 13 minutes video released 9minutes ago and people giving comment 7 minutes ago , god save our attention span

Thank you for the explanation of the Band Gap.

Very good way of explaining semiconductors

Super looking forward to this! For those who don't quite grasp: sometimes all that's needed for the technology to become viable is to reduce production costs/efficiency at scale. If one chips away for 10 years, iterating processes 10% here, 20% there -- it accumulates and can push the technology over that threshold.

We could already have had phone batteries that lasted a week, but the marketplace decided ever-more advanced phones were more important than battery life.

Amazing video as always. Thanks alot.

Excellent presentation Sir.

Graphene potential is amazing. I've been following its progress since 2006 when I first heard about it.

Excellent Analysis, Deployed Worldwide Through My Deep Learning AI… Thank You

This isn't the first time I hear about graphene chips, but last time I checked on the subject, someone suggested a silicene alternative that - in theory - would be easier to engineer since computer chips use silicon anyway.

thank you for all the work and the great content you are offering!

"deficit" != "defect"

Great video. 👏👏

Outstanding video and outstanding music.

It feels like another one of those wonderful discovery you never end up seeing on the market.

Love clicking on a video and seeing work from my college. Thanks for bringing more light to this topic!

The potential for revolutionizing our devices with longer battery life and faster speeds is mind-blowing. The technological breakthroughs we've seen in the past decade continue to astound me.

*Methods for Bandgap Engineering* *_Several techniques can be employed to induce bandgaps in graphene:_* _1. Chemical Functionalization: By attaching functional groups or molecules to graphene, the electronic properties can be altered, introducing bandgaps. This method offers tunable bandgap widths but may suffer from stability issues._ _2.Graphene Nanoribbon Formation: Narrow strips of graphene, known as nanoribbons, naturally exhibit bandgaps due to quantum confinement effects. By precisely controlling the width and edge structure of nanoribbons, the bandgap width can be tailored._ _3.Strain Engineering: Applying mechanical strain to graphene can modify its electronic properties, including inducing bandgaps. This approach offers a reversible method for controlling conductivity but requires precise manipulation._ *Implementing in Transistors* *_To utilize graphene as a semiconductor in transistors:_* _Fabrication: Begin with a graphene layer on a substrate, typically silicon dioxide._ _Bandgap Introduction: Employ one of the aforementioned techniques to introduce bandgaps into graphene._ _Electrode Integration: Add source and drain electrodes to facilitate electron flow._ _Gate Control: Utilize a gate electrode to modulate the conductivity of graphene by adjusting the bandgap width._

Apple's Sillicon was the most powerful recent improvement in terms of battery life in laptops and much faster performance, hope to see more of this type of technology

I LOVE technical videos like this!! Thank you D.A.!!

This is what makes me so excited not only devices can run many degrees Celsius cooler but they could run thousands of times faster without making as much heat as regular silicon

Holy, this is incredible, I remember when I first heard of graphene. Now to actually see it being able to be used is amazing. I can't wait to see what all comes from this discovery.

Please keep making videos on this topic

Looks like there was hiccup in KZfaq again. I got unsubscribed. So everybody make sure you are still subscribed. YT's system is so odd sometimes.

Graphene is one of those technological breakthroughs that is always 10 years away. Just like Nuclear fusion. I am afraid AGI may follow the same trajectory

Great video, keep up the good work.

Great video! This is really interesting!

You didn't mention what the "height" of the ladder steps represents, which would make it hard to understand what the gap is supposed to refer to for anyone who doesn't already know that we're talking about energy levels.

We're so fucking back bro

Thanks for sharing it. ✌️

Interesting stuff, quite a break thru. Be interesting to see how long it takes to get in to consumer devices.

As Elon said it ,"prototype is easy but mass production is Hard.

I have been following the same research and I was really excited when they announced. I finally felt Carbon chips were near.

Awesome!! also, like the lightening at the end of the video...

That's something I'll be eagerly waiting for.

we have been hearing these things for over 10 years and we have not seen anything on the ground

Wow. That means pictures of kittys at light speed, high performance scams and non stop advertizing...... Can't wait.

<a href="#" class="seekto" data-time="172">2:52</a> Graphene can be, and usually is, a mix of molecules with various thickness (ie. different number of connected layers). The 1-layer graphene is called monolayer. There are other forms of graphene with gaps in the sheet(s), 3D arrangements, etc.

You are watching coldfusion tv! Love hearing that great video!

We’ve been hearing about twice as fast processors and half the size 10 times better batteries every year for 20 years. It’s never happens either because it’s not possible or those up top who get rich don’t allow it.

Sounds neat, but big skepticism until I see a commercial product.

We hear about this for a very long time. Maybe make a video about why it is still not being used.

I feel the need to point out that, faster clock speeds are not simply limited by the silicon. As clock speeds increase, you start to have a problem where the signals are bIeeding through as RF noise faster than they are traveling across the intended circuit. If the signal "jumps" the circuit gap, then you start to have all sorts of timing problems and the circuit would become increasingly noisy. So, a lot of the circuitry would have to be replaced by opto-electronics which would drive the prices sky-high!

The problem you speak of at the end (current leakage) can be solved while scaling down the transistors. When researching problems with leakage at sub nano level it was actually discovered that taking advantage of quantum interference of electron by sending waves shifted by PI you can actually achive near-zero current leakage.

To everyone complaining in the comment section. All the “future” tech that disappeared or “isn’t being used yet” is being used they just aren’t consumer products. So many wild things have existed in history that weren’t consumer products.

<a href="#" class="seekto" data-time="728">12:08</a> The Deus Ex Universe is arriving faster than ever before

Love you work! Another great story on innovation. Now this is a GAME CHANGER.

Terraherz instead of Gigaherz, so your phone is 5x as fast. Strange calculation

I'm a simple guy, I see Dagogo's post. I watch. Straight up

Great broadcast

"Electrons can only be in a few discrete layers, or shells, above the nucleus, which we can call bands" A band is not the same as a shell. A shell is what you get if you have more-or-less isolated atoms (or molecules), like in a gas or a liquid. A band is what you get in denser materials such as crystals, and it's a collective thing involving the entire structure of the material. A shell only allows one energy (e.g. the ground state of the hydrogen atom has an energy of -13.6 eV, take it or leave it), but a band allows a whole _range_ of energies, which secretly are like lots of little shells extremely close together, and shared across the entire material.

My PhD studying electrical properties of graphene convinced me that it will never move beyond an academic curiosity. It’s totally impractical to work with even when you move beyond the exfoliated flake method.

Fyi, for those of you other there that like building your own pc, they make Graphene thermal pads that take the place of thermal paste for CPU's. Personally, I even take my GPU apart and put a pad on the GPU dye. I've used the same pad for years now, even reused a couple in multiple builds, still working great.

Yes more technical videos please!!

I have to admit it's quite fun to watch people talk about things they have no understanding of.

Lol, my gaming laptop last for the length of a movie, then it needs to be charged. It's utterly useless without consistent power.

gaslight, gatekeep, graphene

Graphene is the way of the future but calling it "2D" is like calling a piece of paper a "line segment"

Really nice. Would be nice to see a product.

ColdFusion can you please give credit to the other university that collaborated with georgia tech to do this. You forgot to put Tianjin University in collaboration. GIve credit where credit is due please

Computing really needs to take a chill pill!!!

Hey, I remember listening to the Gap Band, great music.

Thank You
