标题： Quantum Capacitance of Graphene Sheets and Nanoribbons

摘要： 本章介绍了用于计算单层和双层石墨烯及其纳米带的量子电容的半解析模型。 由于电子-空穴液滴是所有石墨烯样品中的实验事实，它们已被纳入我们的计算中。 还研究了电荷中性点附近的量子电容的温度依赖性，获得的结果与最近在单层和双层石墨烯器件上的量子电容测量中观察到的许多特征一致。 此外，考虑了石墨烯纳米带的有限尺寸和边缘效应的影响，同时考虑了GNRs能带结构中的边缘键松弛和第三近邻相互作用。 显示英文摘要

摘要： In this chapter, semi-analytical models for the calculation of the quantum capacitance of both monolayer and bilayer graphene and its nanoribbons, are presented. Since electron-hole puddles are experimental facts in all graphene samples, they have been incorporated in our calculations. The temperature dependence of the quantum capacitance around the charge neutrality point is also investigated and the obtained results are in agreement with many features recently observed in quantum capacitance measurements on both monolayer and bilayer graphene devices. Furtheremore, the impact of finite-size and edge effects on the quantum capacitance of graphene nanoribbons is studied taking into account both the edge bond relaxation and third-nearest-neighbour interaction in the band structure of GNRs.
