Solid State Physics Course (Physics 4309-5304) Lectures
Note: Some Lectures (Power Point) are under construction!
A GOAL
is to post a lecture before we discuss a topic in class, but I can't promise!

Phonons II: Thermal Properties
(Material from Kittel's Ch. 5 plus many outside sources.)
Note, except for Part I, all lectures here were prepared by others & found on the internet.
I've posted more than one discussion of each topic in order for you to read more than one viewpoint on each topic. Looking at the same physics concepts from more than one viewpoint will hopefully increase your understanding. NOTE! Thermal Properties of materials can still relevant to modern research!! See a 2008 Publication by me, with students & collaborators: "Thermal Properties of Guest-Free Si136 and Ge136 Clathrates: A First-Principles Study," K. Biswas, C.W. Myles, M. Sanati,  & G.S. Nolas, Journal of Applied Physics 104, 033535 (2008). Download it Here.
