I'll be in my senior year next year, taking Solid State in the fall. I've taken Thermal, E&M, QM, Modern, Mathematical, Stat Mech, and a few circuit labs. I'm just not sure if taking SS would be worth it for me. The course description makes it out to be what we just did in Stat Mech this quarter, but more in depth. We sort of covered conductivity with things like band gaps and phonons and Fermi Gasses in Metals. I don't know what I want to do yet in graduate school, though. I really would like to do something with a direct application, like nano-electronics or quantum computing, but those are the only ones I can think of off the top of my head, and I know there are HUGE fields in physics that are directly applicable to life, I just don't know of them. Instead of SS I was thinking of taking an Electronics course, something a bit more indepth than "here is a resistor". Does anybody have any advice for me?
