Abstract Using a generalized Hubbard model within the framework of Kubo formalism, the concentration and temperature dependences of thermo-emf (α) in materials with charge ordering are calculated. It is shown that in a charge-ordered state a threefold inversion of the sign of a occurs with change in charge carrier concentration (n). Temperature reduction leads to a phase transition of the crystal into a charge-ordered state, which at certain values of n also causes a change in the sign of α.
