Answer to Question #292923 in Atomic and Nuclear Physics for Vivek

Question

Problem-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

$p=ne^{-\frac E{kT}},$

$p=n,\implies$$k=\frac ET=305~K.$
