Temperature dependence of the intrinsic spin Hall effect in Rashba spin-orbit coupled systems

Journal Article


Abstract


  • We investigate the temperature dependence of the intrinsic charge and spin transport

    in two-dimensional semiconductors with Rashba spin-orbit coupling. For 2akF 2ma2/h2 << w <<

    2akF 2ma2/h2 ( where a is the Rashba spin-orbit coupling parameter), the real part of the optical

    conductivity sR and the imaginary part of the spin Hall conductivity shI decrease with

    temperature monotonically. Outside this frequency range sR and shI exhibit resonant

    behavior. At high frequencies, sR and shI change sign at a characteristic temperature T1. Our result

    suggests that the sign and magnitude of sR and shI can be tuned by changing the temperature.
