Abstract:We present a theory of phonon-drag thermopower, $S_{xx}^g$, in MoS$_2$ monolayer at a low-temperature regime in the presence of a quantizing magnetic field $B$. Our calculations for $S_{xx}^g$ consider the electron-acoustic phonon interaction via deformation potential (DP) and piezoelectric (PE) couplings for longitudinal (LA) and transverse (TA) phonon modes. The unscreened TA-DP is found to dominate $S_{xx}^g$ over other mechanisms. The $S_{xx}^g$ is found to oscillate with the magnetic field where the lifti… Show more
