I was going through an example of conductors and insulators in terms of energy gap and that got me thinking. For conduction, free electrons need to be able jump from the Valence band to conduction band. Let's suppose the temperature of the material is 0°K, which is absolute 0. At absolute cold, even the atoms, and subatomic particles will cease motion. If the temperature is 0°K, then even in conductors, which have no forbidden gap between the conduction and valence band, there would be no motion of particles and hence, even the conductor would be an insulator. Am I right? If no, then please elaborate how. Thanks in advance.
