Q 1) What are electron, hole, intrinsic carrier concentration, and energy band gap in Si with (a) Nd = 4x10" cm " and Na = 1x10" cm" and (b) additional 6x10" cm ' of Nd? Note: use Effective density of conduction band = 2.8 x 10 " cm'. Effective density of valance band =1.04 x 10 " cm. T= 300 K, Boltzmann constant = 1.38x 10" Kg s*K'.
