Abstract
The thermal transport properties of the electrons in stanene nanoribbons (SNRs) and graphene nanoribbons (GNRs) are studied using a nonequilibrium Green's function approach in which the effects of electron-phonon coupling are considered. The results demonstrate that the electron thermal conductance values in both SNRs and GNRs are closely related to both the temperature T and the chemical potential μ. Comparison with the thermal transport properties of GNRs shows that the quantized thermal conductance plateau in SNRs is narrower at low temperatures, while the thermal conductance is also greater at higher temperatures in SNRs. The periodic strain-induced electron-phonon coupling can modulate the thermal conductance periodically in both SNRs and GNRs.
