Answer to Question #295750 in Atomic and Nuclear Physics for Kundan

Question

The intrinsic temperature of a semiconductor is the temperatures at which the intrinsic

carrier concentration equals the impurity concentration. Find the intrinsic temperature for a

silicon sample doped with 1015 phosphorus atoms/cm3

.

Answer 1

$n=(\frac{M_1}{M_2})^{\frac 32}(\frac T{300})^\frac 32\cdot 2.5\cdot 10^{19},\implies$

$T=41~K .$
