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.

Semiconductors can become conductive if their temperature is raised sufficiently to populate the (empty) conduction band from the highest filled levels in the valence band. The ratio of the populations in the highest level of the conduction band to that of the lowest level in the conduction band is nconduction/nvalance = gconduction/gvalance e–ΔE/kT where ΔE is the band gap, which is 0.661 eV for Ge and 5.5 eV for diamond. Assume for simplicity that the ratio of the degeneracies is...
