We study the heat transfer between graphene and amorphous SiO(2). We include both the heat transfer from the area of real contact, and between the surfaces in the non-contact region. We consider the radiative heat transfer associated with the evanescent electromagnetic waves which exist outside of all bodies, and the heat transfer by the gas in the non-contact region. We find that the dominant contribution to the heat transfer results from the area of real contact, and the calculated value of the heat transfer coefficient is in good agreement with the value deduced from experimental data.
我们研究了石墨烯和非晶态二氧化硅之间的热量传递。我们既包括了真实接触区域的热量传递，也包括了非接触区域表面之间的热量传递。我们考虑了与所有物体外的消逝电磁波相关的辐射热传递，以及非接触区域中气体的热传递。我们发现，热量传递的主要贡献来自真实接触区域，计算出的热传递系数与从实验数据推断出的值非常吻合。
