Theoretical model obtained in momentum space for charge transport in a system consisting of noninteracting polarons

We have developed a theory of charge transport in a system of noninteracting polarons. The theory is conducted to a compact relation through a nonperturbative method based on electron-phonon Hamiltonian. The derived final result represents two different limits of band and phonon-assisted transport,...

Zusammenfassung:We have developed a theory of charge transport in a system of noninteracting polarons. The theory is conducted to a compact relation through a nonperturbative method based on electron-phonon Hamiltonian. The derived final result represents two different limits of band and phonon-assisted transport, which depends on temperature and electron-phonon coupling strength.
