Question

at zero is Kelvin the germanium is​

Answer 1

at zero kelvin germanium is an insulator becoz electron do not transmitted valance band ro conduction band

Answer 2

Answer:

Germanium behaves as an insulator at zero temperature.

Explanation:

Germanium is the pure semiconductor.

Semiconductor behaves as an insulator at zero temperature.

Because we decrease the temperature.

The conductivity of the semiconductors decreases.

Semiconductors behave as an insulator at low temperature.

At zero temperature, the valance band completely fill.

Hence, Germanium behaves as an insulator at zero temperature.
