优化石墨烯的光热电效应

Optimizing the photothermoelectric effect in graphene

Aleandro Antidormi, Aron W. Cummings

摘要:

在其众多用途中,石墨烯在光学和光电应用方面显示出巨大的潜力。特别地,基于石墨烯中的光热电效应(PTE)的器件可以提供具有高信噪比的强且快速的光响应,同时消耗最小的功率。在这项工作中,我们讨论了如何通过调整光限制,器件几何形状和材料质量来优化石墨烯PTE光电探测器的性能。这项研究应该被证明是有用的设计设备使用的PTE在石墨烯,应用包括光学传感,数据通信,多气体传感等。

英文摘要:

Among its many uses, graphene shows significant promise for optical and optoelectronic applications. In particular, devices based on the photothermoelectric effect (PTE) in graphene can offer a strong and fast photoresponse with high signal-to-noise ratio while consuming minimal power. In this work we discuss how to optimize the performance of graphene PTE photodetectors by tuning the light confinement, device geometry, and material quality. This study should prove useful for the design of devices using the PTE in graphene, with applications including optical sensing, data communications, multi-gas sensing, and others.
