At zero degree kelvin a piece of Germanium

Question

At zero degree kelvin a piece of Germanium (A) becomes semi-conductor (B) becomes good conductor (C) becomes bad conductor (D) has maximum conductivity.

Tardigrade Admin · Accepted Answer

Germanium in the pure form is a semiconductor at room temperature and has enough electrons to conduct electricity. However, at zero kelvin, it behaves like an insulator as at this stage, the electrons are in the bonded arrangement and are not free for conduction.
