Question

Derivation of law of mass action in semiconductors

Answer 1

Under thermal equilibrium the product of the free electron concentration {\displaystyle n} and the free hole concentration {\displaystyle p} is equal to a constant equal to the square of intrinsic carrier concentration {\displaystyle n_{i}}. The intrinsic carrier concentration is a function of temperature.

The equation for the mass action law for semiconductors is:[1]
