Coulomb correlation effects in variable-range hopping thermopower

Expressions are presented for describing the variable-range hopping thermopower cross-overs from the Mott T(d-1)/(d+1)-behaviour to the temperature-independent behaviour as the temperature decreases for both two-dimensional (d = 2) and three-dimensional(d = 3) cases. The cross-overs show a profound manifestation of the Coulomb correlation along with that observed in resistance cross-overs. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
