摘要

本文的目的是研究石墨烯等离子体在太赫兹的应用。研究了石墨烯单层对电磁波的吸收范围，以了解石墨烯在图案化SiO2衬底上的等离子体行为。仿真结果表明，石墨烯的掺杂程度、光栅的周期性和衬底上介质的周期性会改变吸收范围和强度。这些结果表明，等离子体效应对石墨烯具有可调谐的行为，可以用于未来中红外区域的等离子体传感器和光电子器件。

Enhanced absorption in graphene on periodic patterned SiO2 substrate

The aim of this paper is to study graphene plasmonics for THz applications. The range of absorbance of electromagnetic waves on a graphene monolayer is investigated to understand the plasmonic behaviour of graphene on patterned SiO2 substrate. Simulation results show that absorption range and intensity gets altered according to the graphene doping level, periodicity of grating and dielectric media used on the patterned substrate. These results show the plasmonic effect on graphene has a tuneable behaviour, and it can be utilised for the future plasmonic sensors and optoelectronics devices in the mid-infrared region.
