Number of holes in valence band, Electrical Engineering

Assignment Help:

Number of holes in valence band:

Derive the expression for number of holes in valence band and Fermi level in an intrinsic semiconductor.

(b) By that percentage does the conductivity of intrinsic Ge at room temperature increase per degree rise in temperature ?

Sol. (b) We know that at room temperature when temperature is increased by 10, then conductivity goes to double. i.e. with 10 increment in temperature, conductivity will be = 100% with 1 increment in temperature, conductivity will be = 10%
