||CleanLecture 22: Antiferromagnets||We finish off the low temperature corrections to the magnetization in a ferromagnet due to spin wave excitations, and also calculate the energy and heat capacity of spin waves. Now, on to antiferromagnets, where neighboring spins are antialigned. We deriv||11 4 2006||Free||View in iTunes|
||CleanLecture 13: p-n Junctions||We talk more about holes today. They don't really exist, you know! But when only a few electrons are missing from the valence band, it's so much more convenient to describe only the missing states that the fictional particles we call "holes" are a very us||8 3 2006||Free||View in iTunes|
||CleanLecture 5: Heat Capacity||We define the heat capacity, and calculate the phonon heat capacity in the high and low temperature limits. We also introduce the density of states. Technical difficulties meant that this lecture did not get recorded this year. In its place, I post last y||9 2 2006||Free||View in iTunes|
