Abstract:

We developed a theory of charge transport in a system of non-interacting polarons. The theory was conducted to a compact relation through a nonperturbative method based on electron-phonon Hamiltonian. The derived final result represents both two different limits of band and phonon assisted transports which depends on temperature and electron-phonon coupling strength.
