Question

At zero Kelvin,all metals have zero resistance

Answer 1

Theoretically if a few laser-cooled metal atoms could actually reach absolute zero and no longer had any velocity, we would be able to define their momentum as being truly zero. ... At absolute zero which means zero momentum, the uncertainty in position would be infinite.

Intrinsic Semiconductor at T = 0K

At T = 0K, an intrinsic semiconductor will behave like an insulator. Structurally, there is a small energy gap between the valence and conduction bands in a semiconductor. When the temperature is low, the electrons are not excited enough to jump to a higher energy state.
