"Do you need me to do anything?" "Yes, but I dont know what." Felt that ngl😂

This is awesome, science doesn't get much more raw than this! Not often you get a look into things like this.

I'm three videos in. This channel is way too underrated.

We live in a truly unjust universe if it's true that only a few hundred people have viewed these videos. I heartily thank Steve Mould for mentioning you. I'm now three videos in to your library and have seventy more to watch, because it sure looks like everything you've produced is MUST SEE amazing science.

Now that we know WHY it has to work like that, I wanna know WHAT those coatings are used for...

Your channel is the definition of underrated

Holy cow. Just found this channel from Steve Mould's shoutout in his recent video. I'm loving the mix of hard sci (with wonderful, layman's explanations) and the other projects and stuff (photography). Way to go, keep it up! I remember stumbling upon a random channel called "Cody's Lab" many many years ago. Just a kinda quirky guy with a couple thousand subscribers. Was cool to see his channel grow and grow (but not change all that much). He's now got almost 2 million subscribers and hundreds of thousands of people watch every video he makes. It's obvious that you aren't in the mindset of "chasing views" and you clearly make videos about things you're just simply interested in. I'm sure you don't need my encouragement to keep going, but your content is so authentic and interesting, don't be surprised if one day you wake up and find that your channel has blown up. There's no substitute for authenticity. Or, put another way, "real recognize real". Anyway just wanted to say hello and say thanks. --J

What the hell?! I understood everything this guy said

Your level of explenation cant be defined almost its just so perfect for getting people with no knowledge about a subject to understand. Keep up the amazing work, you earned yourself a subscriber

I've never heard of this side of science.its fascinating

I love that the way we produce things like doped semiconductors is essentially the same way that they (probably) make LaCroix; Silicon that was in the same room as a hot piece of Gallium vs carbonated water that was in the same room as a raspberry.

These videos are really cool. I love learning about this kind of very niche high tech research equipment. And not to be the first to say it but this channel is definitely underrated. Also, as a programmer, a particular thing that fascinates me is the software that controls all this stuff. Specialized single purpose programs that have to integrate with this the crazy equipment is wild, but maybe I'm just a big nerd for weird things. It's just such an enigma.

This is the best depiction of MBE I have ever watched!

These MBE videos are really interesting, I've tried asking my professors about MBEs, but only one was familiar with it and only from reading. Really neat piece of equipment

Working with RF Sputter deposition at my job, it's always fascinating to me to learn about different methods of depositing metals.

I am much enjoying your series on your equipment. My father built similar equipment for Westinghouse several years ago to facilitate precision electron beam welding equipment and vapor deposition equipment for precision coating. They were test systems to provide proof of concept equipment and develop the technology to where it could be marketable. The vacuum pumps he used were very impressive to my teenage self. The system was housed in a small cylinder, inside a booth the size of a small room to provide a two stage vacuum tight sealable enclosure, as the working surface had to be somewhat larger than those you are dealing with. There were,as I recall, three stages of vacuum pumps working on different principals to obtain the required levels of vacuum. On the other hand I suspect his allowed target area might have been somewhat larger than that you work with and the precision you deal with may require another order of magnitude of vacuum than Dad's system did. Dad built all manner of things as prototypes for Westinghouse. Engineers came in with fancy designs and schematics and Dad helped them to scale there sometimes unwieldy plans into something that might actually be capable of being built. Your lecture on how your equipment works is "deja vu all over again" to quote Yogi Berra.

This has literally blown my mind. Always wondering how these processes were undertaken and never knowing **fully** the actual method, you've opened doors in my mind like the day when I first learned how transistors work. Thank you for this video, your time, and looking forward to more mind blowing insights into how we accomplish the very small and precise.

It is not fair just how at ease with life this guy is

Flipping heck! I found a nerdy physist that I can look up to. This guys terminology is way out of my limits. I will be following your future projects very closely to learn something new from you.

I'm so honored to be in on the underground science KZfaq community. That being said I am sharing this with everyone I know that loves science! What a wonderful time to be alive!

one of my favorite new channels i've found, reminds me of codylabs back when he started. subbed

Wow! So happy I found this channel. Thank you for taking the time to explain so carefully. Must have taken a lot of time. Please keep it up!

I've watched a decent amount of your videos, and am subscribed, but usually they are just on one off projects or experiments. These videos on your day job are crazy interesting. Great video!

Interesting content, idk why youtube is recommending this now. I've watched applied science and other science youtubers for a few years now and this channel is only revealed now

I'm part of the new wave of subscribers, but I'm so glad that you seem to be blowing up as of late. This is an absolutely amazing channel.

I still have absolutely no idea what you do with the thing after you've made it, but the process is fascinating!

Remember babysitting a MBE machine at Boston Lasers. The machine had a malfunction and got a couple extra shots of trimethyl aluminum and we rolled with it. Made orange 604nm lasers instead of red 633nm ❤

This is some of the most interesting stuff I have ever seen.

this really gave me an appreciation of material engineering what I imagined is just chucking random metal into a crucible and testing it until you find the perfect blend

Your channel is unironically and literally the coolest thing I've experienced all year

I love this series please continue it!!

I knew atoms were tiny and all, but to say that 30 million is coming off a screw like that really sheds light on how they are much much much much smaller than one may think.

This is neat and It just reminded me that "Molecular Beam Enigma" was the name of my electronic music album in middle school. idk why.

I walked through an MBE lab a few years ago and seeing the massive vacuum vessels blew my mind! Thank you for such an awesome & detailed breakdown of what is going on. Such fascinating science & Truly amazing machines. Thanks again

2:00 That is a top notch over simplification. 11/10

this is the most interesting thing I've seen on this channel yet, and I've really liked most of it already!

Pretty awesome insider look into a vacuum deposition chamber. Thanks AP!,💆

So glad I found your channel! This is best use case for KZfaq imo

Incredibly fascinating! Keep doing what you do!

i would love to see more of these... like, one in a quantum mechanics experiment. we lay people just see these masses of metal and wire... this video made these materials and machines so much more understandable and down to earth. a walk through of a quantum mechanics experiment i think could do a lot for making the "ultra high tech" appear more normal, less intimidating, down to earth

I don't know if you've mentioned the company or university you're working at, but it's very cool of them to allow this sort of filming in what looks to be a many-million-dollar lab!

As an electronics technitian i find this awesome. Thank you so much for this much detail during the explanation.

lots of info, superb and joyful explanation without getting bored with such heavy content

Your videos are very very informative, very high quality and everythings so modern and cutting edge. I really like this one. Keep up the good work!! Young and energetic personality inspires up well too much!

This was awesome. Thanks for sharing!

This is amazing. What a great service.

Incredible. I wish I knew physics more. Not one of my priorities to learn it atm but I wish it was as intuitive to me as it probably is to you. I probably got recommended this due to looking into PCB manufacturing stuff, and honestly deposition as a topic really fascinates me in all the forms it takes. Thank you for the video!

very interesting video. I once applied for a job where this procedure was used, it was for layering a protective coating on custom-ground eyeglasses for a very well-known manufacturer. The machine was similar where there was a substrate that was incinerated in a vacuum and the vaporized material would evenly deposit onto the glass.

Excellently described, very interesting, thank you

this was awesome! very well explained and visually rich!

2 questions: 1: how do you avoid accumulating material that radiates from the vacuum chamber itself? For example, if the chamber is steel would you get Iron impurities in your crystal that you are growing? 2: what causes the atoms to eject with force from the evaporating sample? And what speed do these atoms travel at when ejected? Are they just randomly bouncing around until they impact the substrate or are they actually fired in a beam like you described? P.S. great video btw! I love your content. Especially things like this where you have access to equipment that most others don’t and can explain it.

Damn, sounds very complicated yet interesting.

Your videos are truly amazing and they make me consider switching from ChemE to Mats.

Pretty cool. Great explanation.

Awesome video, nice animations and easy to understand explanations! Thank you!

Fascinating! Thank you!

This is a ridiculosly good explanation of the topic, amazing

Excellent presentation as always buddy. Keep it up

You're so good at explaining.

Love these videos. This is such a cool topic

I can’t even believe how much I can learn in 10 minutes. Really interesting stuff and really well presented!

this was simply awesome !! loved it loved it loved it !!!!!!!!!!

this channel is amazing!

This was understandable and fascinating

the amount of technology that goes into this stuff is absolutely unbelievable. it's no surprise that it took us 12000 years to reach this level.

Really neat! I did an internship that involved PLD and it was a pretty wild time getting up to speed. I think by the time I was done, I was just barely starting to understand what was going on. Wish I could have kept going, but my area of study was actually completely unrelated. Don't know why the algorithm recommended this channel *now* but I'm glad it did.

Very well done. Thanks.

Thank you very much for this video! Science at it’s finest

Dang your videos 📹 are so cool. You explain things really well.

Fascinating!

Cant wait for you to be the next addition to the Rober, SmarterEveryday, Backyard Scientist, etc crew. Your going to go far on this platform keep up the good work!

Wow Wow. MBE epitaxy. Thanks for your explanation.

Man... this is fascinating. I need to get into this career field...

Another great video 👍

It's just like going back to apprenticeship/college we still had to learn the ins and outs of just about every electronic valve in use

Great video mate!

Very interesting. Thanks!

Another Steve Mould convert here. Loving the channel. I have two questions from this video. 1. How do your shutters work without losing the vacuum? Are they magnetically controlled? Looked very mechanical at 9:18 2. Are you able to ignore the evaporation of the pressure vessel itself because it isn't a focused beam from a heateed source? It seems to be a few orders of magnitude bigger than your bolt head.

Finally, this isgreat insight! Thank you:)

2:49 very good analogy...

So you have to have steady hands to do this job. somehow thought it would be more controlled. Very interesting and cool!

What an amazing vocation you have, thank you for sharing what you do. Very interesting, very interesting indeed. P.S. Out of interest do you do batches of a certain material, then have to clean the machine between batches or is it only certain types of materials/alloys that are very very sensitive that necessitates cleaning the entire machine?

This reminds me of the short story "Uncommon Sense" by Hal Clement, about life on a hot airless planet.

Very very cool I understood pretty much most all of it

Very cool vid!

Lots of questions: Do you need to cool the target? What stops the material coating the walls of the vacuum vessel? How do those pressure gauges work?

Thank you sir for the highly interesting and weirdly gratifying procedural commentary. Vacuums are virtually tasty, despite the 0 yoctograms of flavoring.

Thank so much you for making this type of content, if it wasn't for you I don't know how else would I be able to learn or just know about that !!! =)

i wish there were more people like you🙏...especially in biotechnology

I love this so much

It's almost unbelievable what we are able to do. I love science!

Fascinating

Subscribed! This is exactly what I'm asking.

somehow just discovered this channel. subscribed.

the intro alone has evaporated 20,000,000 atoms of my brain matter

This could be a good stepping stone to demonstrate how vacuum tubes work. Then how semiconductor doping works.

like others below have mentioned, this is really cool...keep these videos coming...

This guys animations make me laugh.. XD great content! subbed

I liked this, would like to see more about your work if you get the chance

Awesome!
