锯齿形石墨烯纳米带中电子输运的研究
Aspects of electron transport in zigzag graphene nanoribbons
摘要：
利用非平衡格林函数方法研究了锯齿形石墨烯纳米带中的电子输运特性。后者是介观物理学中的一种深奥的工具，使用这种工具，通过考虑系统内的势阱来进行分析。在此势阱中，讨论了透射系数、局域态密度（LDOS）和电子输运性质与单胞原子数的关系。我们观察到电子和热导率随着原子数的增加而增加。除了这些之外，还研究了取决于这些输运性质的品质因数，并且我们发现电子对提高品质因数的贡献在交叉温度以上是重要的。
英文摘要：
We investigate the aspects of the electron transport in the zigzag graphene nanoribbons (ZGNRs) using the non-equilibrium Green's function (NEGF) formalism. The latter is an esoteric tool in mesoscopic physics and using this tool the analysis is performed by considering the potential well within the system. Within this potential well, the dependence of the transmission coefficient, local density of states (LDOS) and the electron transport properties on the number of atoms per unit cell is discussed. We observe that the electron and thermal conductance increases with the increase of the number of atoms. In addition to these, the figure of merit which depends on these transport properties has also been studied and we find that the electrons' contribution to enhance the figure of merit is important above the crossover temperature.
