Physics 140. Fall 2018. Physics and Astronomy Department. Saint Mary's College of California
This course is an introduction to solid state physics. Topics include crystal structure, mechanical properties, thermal properties of the lattice, electronic properties of metals, semiconductors, and magnetism. Prerequisites: Physics 14 and Math 39.
This course is an opportunity to understand the principles used to describe various solid state phenomena, study applications of theory to real world problems, gain further experience with mathematical techniques used in physics and engineering, and develop confidence in using previously learned material to understand new topics.
