The condensate state of excitons in semimetal/semiconductor materials has been considered by analyzing the excitonic susceptibility function in the 2D extended Falicov-Kimball model including the electron-phonon interaction. The excitonic susceptibility in the system has been calculated by using the Hartree-Fock approximation. |
