Question

Describe the difference of temperature dependence in the electrical conduction of intrinsic semiconductors and metals/alloys; and
b) Explain the origins of different temperature dependent electrical conduction behavior in extrinsic and intrinsic semiconductors at intermediate temperature? However, at high and low temperature regions why extrinsic semiconductors seem to exhibit similar electrical conduction behaviors as the intrinsic counterparts? Use sketches and/or equations if necessary.
