A sample of N-type semiconductor has electron density of 6.25 x 1018/cm3 at 300k. If the intrinsic concentration of carriers in this sample is 2.5 x 1013/cm3 at this temperature the hole density works out to be-A-106/cm3B-108/cm3C-1010/cm3D-10l2/cm3-B-108/cm3

Question

APTITUDE CRACK · Accepted Answer

B 108/cm3 Ni^2 = Ne*Np. Np = Ni^2 / Ne, Np = (2.5x10^13)^2 / 6.25x10^18, Np = 10^8.
