Thermodynamic properties of two-dimensional semiconductors with spin-orbit coupling

Journal Article


Abstract


  • We present a quantitative analysis on the effect of Rashba spinorbit interaction on the thermodynamic properties of two-dimensional

    semiconductors. Quantities such as the Helmholtz free energy, the electron internal energy, the electron entropy and the electron heat

    capacity are calculated as a function of temperature and the spinorbit coupling strength. It is shown that the free energy decreases with

    the spinorbit coupling while entropy increases with the spinorbit coupling. At the temperature of around 10% of Fermi temperature,

    the reduction of free energy due to Rashba coupling alone is round 15%.
