Question

The intrinsic semiconductor becomes an insulator at
(a) 0°C
(b) -100°C
(c) 300 K
(d) 0 K

Answer 1

option a is correct 0°

Answer 2

Answer:

d) 0 K

Explanation:

An Intrinsic semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities.

At high temperature especially at temperatures where solar cells operate electrons gains energy to escape their bonds. In room temperature the intrinsic semiconductor has free electrons to conduct current.

At absolute zero temperature i.e 0 K the intrinsic semiconductor acts as an insulator.
