Mass action law is not valid for which type of semiconductors in electronic devices?

A)
Elemental
B)
Degenerative
C)
Compound
D)
Compensated

Correct Answer : Option (B) :   Degenerative

Explanation : Mass action law is related to the concentration of electrons and holes in a semiconductor. Degenerative type semiconductors show similar behavior to metal. So, Mass action law is not valid for them.
