Abstract

(formula presented) noise induced by traps consisting of donors with no neighbors with close energies in their vicinity is studied. Such donors slowly exchange electrons with the rest of conducting media. It is shown that in the variable range hopping regime, (formula presented) noise exponentially grows with the decreasing temperature. At high temperatures, when the variable range hopping crosses over to the nearest-neighbor one, we predict a very weak temperature dependence in spite of the activation dependence of the conductivity.
