Thermoelectric figure of merit of bulk nanostructured composites with   distributed parameters
  We consider the effective properties of composite structure that includes nanocontacts between macrocrystallits of bulk material. The model of a such nanostructured composite is developed. In the mean-field approximation we calculate effective values of the thermopower, heat - and the electrical conductivity, thermoelectric figure of merit.
