Which of the following effects is responsible for violating the mass action law in degenerative type semiconductor electronic devices?

A)

Thermal effect

B)

Electronic drift effect

C)

Lattice vibration effect

D)

Bandgap narrowing effect

Correct Answer : Option (B) : Electronic drift effect

Explanation : With a very high amount of doping in degenerative type semiconductors, atoms come closer. For this reason, the interatomic interaction cannot be neglected. So, the effective band gap becomes narrow.
