Homework Statement Hi all I can't seem to figure out, why semicodunctors do not have Fermi surfaces. At T=0K, there are no electrons in the conduction band, and thus there is no Fermi surface - all OK here. But at T > 0K, there are electrons in the conduction band. Why is it then that it...

Homework Statement Hi all. Say we are looking at a (pure) semiconductor at T=0 K. Now we turn on the heat, so only 1 electron jumps up to the conduction band per cm3, and likewise 1 hole is created in the valence band per cm3. Does this mean that the current density of this semiconductor is...
