When an n-type semiconductor is heated

A
number of electrons increases while that of holes decreases
B
number of holes increases while that of electrons decreases
C
number of holes and electrons do not change
Correct answer
D
number of holes and electrons increases equally

Solution

When an n-type semiconductor is heated, number of holes and electrons increases equally as when a free electron is produced, simultaneously a hole is also produced.

Hence, the correct answer is option: 'D'.
