(a) The concentration of minority carriers in an extrinsic semiconductor under equilibrium is inversely proportional to the doping concentration. Justify your answer with proper steps. 5 M (b) In a semiconductor lab, a student is performing the lab experiment, in a p - type germanium, n = 2.1 x 1019 m3, density of boron 4.5 x 1023 atoms m3. The electron and hole mobilities are 0.4 and 0.2 m2 V-1s1 respectively. What is the conductivity before and after the addition of boron atoms? 5 M (a) The concentration of minority carriers in an extrinsic semiconductor under equilibrium is inversely proportional to the doping concentration.
