Is Mass Action Law Only Applicable to Semiconductors at Thermal Equilibrium?

[munna007]

is mass action law only applicable to semiconductor at thermal euilibrium and why?



i don't know what happens with semicounductor at thermal euilibrium...why is mass action law not applicable at non-euilibrium...

The law of mass action is also applied in semiconductor physics to describe the carrier density in a semiconductor. Regardless of doping, the product of electron and hole densities is a material property dependent on temperature.
