✦ Synopsis

Expressions are presented for describing the variable-range hopping thermopower cross-overs from the Mott T Ž dy1.rŽ dq1. -behaviour to the temperature-independent behaviour as the temperature decreases for both two-dimensional Ž . Ž . d s 2 and three-dimensional d s 3 cases. The cross-overs show a profound manifestation of the Coulomb correlation along with that observed in resistance cross-overs.
