Abstract

In the present work, we make use of the theoretical model of electron subsystem for strongly correlated compound with a peculiar density of electronic states (DOS). The energy spectrum has been calculated within the unperturbative approach. The chemical potential and Seebeck coefficient have been calculated numerically for a number of realistic DOS forms for non-integer band fillings. Distinct types of Seebeck coefficient temperature behavior have been attributed to different electron interaction regimes to be realized in some regions of electron band filling and strongly influenced by the DOS form.
