On doping germanium with donor atoms of ...

On doping germanium with donor atoms of density `10^(17) cm^(-3)`, find its conductivity in mho/cm, if `mu=3800 cm^(2)//V-s`.

A

30.4

B

60.8

C

91.2

D

121.6

Text Solution

Verified by Experts

The correct Answer is:
B
Condcutivity `sigma = n_ie mu_e = 10^(17) xx (1.6 xx 10^(-19)) xx 3800= 60.8 "mho/cm"`
