-Reading: Mott's txt bk, A&M p340 & 542
+QHE
-Summary: Disordered semiconducting materials: conductance vs. temperature predicted by variable range hopping theory. Introduction to Mott insulator state. Calculation of critical lattice constant for metal-insulator transition. Little a limit: Thomas-Fermi screening depends on the electron concentration. Big a limit: polarizability depends on the distance to neighboring dipoles.
