Abstract: | Using transport theory, we studied the temperature dependence of the static conductivity and of the thermal emf due to multiphonon hopping in disordered semiconductors. In the low-temperature region when T <
m (
m is the maximum phonon frequency), the temperature dependences of the conductivity and the thermal emf are the same as when single-phonon hopping is dominant. At higher temperatures (T ![gap](/content/tl5216p53727x7j3/xxlarge8819.gif)
m), the hopping conductivity and thermal emf are characterized by a slower dependence on reciprocal temperature than in the low-temperature region.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No.2, pp.42–47, February, 1976.The author is to V. L. Bonch-Bruevich and A. G. Mironov for discussing this work. |
