Abstract: By suggesting a simple density of localized states for amorphous materials and using the percolation method the analytical expression is obtained for describing qualitatively the observed variable-range hopping thermopower crossover from the Mott T l/2 -behaviour to the temperature-independent behaviour as the temperature increases. The crossover shows a profound manifestation of the Coulomb correlation along that observed in VRH conductivity crossover.
