Currently Playing: How to evaporate a metal

CORRECTIONS: [none yet] Welcome to Episode Two of my series about molecular beam epitaxy! In this video, I'm talking about the best way to shoot a beam of atoms at something… As much as that sounds like a crazy scifi weapon, it's actually a great technique for delivering material to a growing crystalline thin film. All materials, even solids, have a vapor pressure and are slowly evaporating. When you put a chunk of material in a vacuum chamber and get it hot, it can evaporate so fast the vapor can be directed towards a target! Let me know in the comments if you have any questions about the MBE I could address in future videos!
