Phonons Memes

When your Shockley-Read-Hall recombination model suddenly transforms into an anime finishing move! Semiconductor physicists spend years studying electron-hole recombination at defect sites, and then some kid with white hair comes along and turns it into a purple energy blast. The phonon emission is just the universe's way of saying "physics has left the chat." Next time your professor talks about band gap theory, just yell "HOLLOW PURPLE!" and see if you get extra credit or detention.
