The present work deals with performance analysis of graphene and graphene derivative-based Nanoelectromechanical (NEMS) switch. The effect of manipulating the beam length and reduction in elastic modulus on pull-in voltage has reported in the present study. It has been found that reduction in elastic modulus reduces the pull-in voltage with less degree of reduction in restoring force than increasing the beam length. Moreover, the finite element analysis (FEA) of single material beam (graphene), and composite beams (graphene/rGO, graphene/GO) has performed. The composite beam concept is a good choice to reduce both elastic modulus and pull-in voltage. The simulation study demonstrates that the pull-in voltage reduces by 20% and 31% and restoring force reduces by 36% and 53% for graphene/rGO and graphene/GO composite beam respectively as compared to graphene beam. The analysis of switching time and release time for all the beam structures have also done. The composite beam based NEMS switch exhibits good performance in terms of pull-in voltage, restoring force, and switching time.

使用基于石墨烯衍生物的复合梁的 NEMS 开关性能分析

目前的工作涉及石墨烯和基于石墨烯衍生物的纳米机电 (NEMS) 开关的性能分析。本研究报告了操纵梁长度和弹性模量降低对牵引电压的影响。已经发现，与增加梁长度相比，弹性模量的降低降低了牵引电压，而恢复力的降低程度更小。此外，还进行了单一材料梁（石墨烯）和复合梁（石墨烯/rGO、石墨烯/GO）的有限元分析（FEA）。复合梁概念是降低弹性模量和牵引电压的不错选择。仿真研究表明，与石墨烯梁相比，石墨烯/rGO 和石墨烯/GO 复合梁的吸合电压分别降低了 20% 和 31%，恢复力分别降低了 36% 和 53%。对所有梁结构的切换时间和释放时间也进行了分析。基于复合梁的 NEMS 开关在引入电压、恢复力和开关时间方面表现出良好的性能。
