Abstract


  • It is shown that in two-dimensional semiconductors, the electron-phonon interaction and polaron

    mass correction are both significantly enhanced by the Rashba spin-orbit coupling. The mass

    correction is positive for the upper Rashba branch and negative for the lower Rashba branch. Both

    Rashba branches have the same polaron binding energy, which is higher than that for systems in the

    absence of spin-orbit interaction. To the leading order, the correction to the binding energy is

    proportional to the square of the spin-orbit coupling strength.
