▎ 摘  要

Thermal transport properties of gapped graphene structure taking into account the effects of interaction between electrons and Einstein phonons have been addressed. Specially we study the temperature dependence of thermal conductivity and thermopower of the structure. Green's function method has been implemented to obtain transport coefficients of the system in the context of Holstein model Hamiltonian. We find numerical results for temperature dependence of thermal conductivity of gapped grapheme for different electron-Holstein phonon coupling strengths. Also the temperature behavior of Seebeck coefficient of gapped graphene structure due to electron-phonon interaction has been investigated. Moreover, we address the effect of gap parameter on temperature dependence of gapped graphene for finite gap parameter.
