Abstract


  • The authors demonstrate that the Rashba spin-orbit interaction in low-dimensional semiconductors

    can enhance or reduce the electron-phonon scattering rate by as much as 25%. The underlying

    mechanism is that the electron-phonon scattering phase space for the upper (lower) Rashba band is

    significantly enhanced (suppressed) by the spin-orbit interaction. While the scattering time

    decreases for the upper level, the mobility of the level increases due to an additional term in the

    electron velocity.
