摘要

利用线性响应理论和Landauer形式，研究了有限温度下弹道石墨烯带的热能。研究了热电能与温度和化学势的关系，所得结果与最近在高迁移率石墨烯带上观察到的许多特征在定性上一致。揭示了短带热功率中的法布里-珀罗振荡作为化学势的函数。

Fabry-Perot oscillations in the thermopower of ballistic graphene ribbons

The thermopower of ballistic graphene ribbons, at finite temperatures, is studied using linear response theory and the Landauer formalism. The dependence of thermopower on temperature and chemical potential is investigated and the obtained results are qualitatively in agreement with many features recently observed in thermoelectric measurements on high mobility graphene ribbons. Fabry-Perot oscillations in the thermopower of short ribbons as a function of chemical potential are revealed.
