Some REAL science for the channel! Growing semiconducting PbSe crystals (MROP 2020 talk)

I've posted a few videos about awesome equipment I get to use in the lab (and plan to post many more because big fancy machines are awesome) but I haven't actually explained any of my research on the channel! Well that ends today, with a real honest-to-goodness conference talk I gave this January. In our lab, we grow "rocksalt" PbSe crystals (with a structure that looks like a 3D checkerboard) on top of "zincblende" InAs crystals (with a structure that looks like a bunch of methanes stuck together).

So bust out your memory of high school chemistry and learn how bonding, charges, and crystalline symmetry all matter to actual scientific research going on right now at UCSB and Stanford!

Big thanks to MROP, the Materials Research Outreach Program, for having me as a speaker, and also big thanks to Ram Seshadri, Director of the Materials Research Laboratory, for giving me the OK to share this recording!

If anybody's ludicrously curious, here's the paper this talk was based on:
