Lecture 11: Metals, Insulators, and Semiconductors

Solid State Physics by Prof. Carlson

Feb 21, 2006Education

Electronic energy levels in simple crystalline solids have a bandstructure to them. (Bandstructure is just energy vs. wavevector or momentum.) Depending on the filling of the bands, the material can either become a metal...
