摘要

石墨烯纳米带最近引起了人们的极大兴趣，因为它们被认为是纳米电子器件的有前途的组成部分。直接带隙和相对窄的带隙随带宽度的可调性使它们成为光电器件，特别是红外应用的合适候选者。采用非平衡格林函数形式，对石墨烯纳米带红外探测器的性能进行了数值分析。

Performance evaluation of graphene nanoribbon infrared photodetectors

Graphene nanoribbons have recently attracted much interest as they are recognized as promising building blocks for nanoelectronic devices. The direct bandgap and the tunability of the relatively narrow bandgap with the ribbon's width renders them as suitable candidates for opto-electronic devices, especially for infrared applications. The performance of infrared photo detectors based on graphene nanoribbons is analyzed numerically, employing the non-equilibrium Green's function formalism.
