The position of the

**Fermi**level is essentially determined by the chargedistribution on the gap states. If the

**Fermi**level is shifted beyond the mobilityedge by doping, the material becomes metallic and its conductivity does not

vanish at absolute ...

**Fermi**level, as in a metal, only thoseelectrons within a range kBT of the

**Fermi**level contribute to the susceptibility.### What people are saying - Write a review
