Question:
(a) Give a definition of electrical resistivity and state how it is related to electrical conductivity.
(b) At 273–290 K, the electrical resistivities of diamond, Si, Ge and a-Sn are approximately 1 × 1011, 1 × 10−3, 0.46 and 11 × 10−8 Ωm. Rationalize this trend in values.
(c) How does the change in electrical resistivity with temperature vary for a typical metal and for a semiconductor?
