As a semi conductor approaches absolute zero there should be zero conductivity, the thermal energy that electrons acquire is or can be responsible for promoting electrons from the valence band to the conduction band to provide current flow in a semi conductor ( for t>0).
My question is shouldn't metals as have zero conductivity as we approach absolute zero?
Even though the fermi level resides inside the conduction band, the electrons without any thermal energy can not access other vacant higher energies?
Does the finitie conductivity of metals at absolute zero have something to do with metals being non perfect lattices (realistically) because of entropy forces imperfections on the lattice.
Can someone explain this better.
Thank you very much
