Epitaxy

[@PerMortensen]

How do you (can you?) ensure that the material gets deposited uniformly, rather than clumping? Can you direct the growth?

[@blessysusan347]

Rotation if I'm not wrong

[@matheusfelipe4183]

Perfect. Simple and direct

Thank you for this clear, concise video!😭

[@ywk7282]

Thank you for this video! May I ask a question? Seeing the process this seems similar to thermal evaporator. What is the difference between the two?

[@operationalfacts5602]

They are similar in a way. The main difference is that with a thermal evaporator the deposition is physical, that is the atoms simple condense on the substrate. In the Molecular Beam Epitaxy the deposition is chemical, that is the vapor reacts with the substrate(I didn't make that clear in the video). The reaction grows a single crystal on the substrate. Below is a link to the various types of deposits. It's a long document but you can start from page 38. That's the beginning of Chemical Vapor Deposition section. www.inrf.uci.edu/wordpress/wp-content/uploads/day4-deposition.pdf

@@operationalfacts5602 UCI?! Zot zot zot!

[@zy8719]

cool

[@iblesbosuok]

Can silicone be applied in this process? Thank you

[@operationalfacts5602]

No for silicone, yes for silicon

[@Laura-Yu]

Think silicone for breast implants, silicon for computer chips😂

Bro who invented this how do you learn about this or figure out where to start researching. Amazing.

[@operationalfacts5602]

I don't know who invented Molecular beam epitaxy. However you can watch the full video from my other channel where this clip is from. It's about manufacturing materials in space. kzbin.info/www/bejne/f4XQq52NjJWAjKM You can also get more info about Molecular beam epitaxy from the link below. en.wikipedia.org/wiki/Molecular-beam_epitaxy
