The intrinsic carrier concentration of silicon sample at 300 K is 1-5 - 1016-m3- If after doping- the number of majority carriers is 5 - 1020 -m3- the minority carrier density is

Ans : (a) By mass action law , n^2_i = np n_i = intrinsic concentration p= n^2_in = 2.25× 10^ 325× 10^20 = 45× 10^10 = 4.5× 10^11/m^3 ...
