[求助] 石墨烯翻译

Later the top-gate graphene FET was fabricated and the saturating transistor characteristics were observed. The saturation velocity depends on the charge-carrier concentration which is attributed to scattering by interfacial phonons in the SiO 2 layer which supports the graphene channel. The electrostatic modulation of
the channel through an effi ciently coupled top-gate yields the
transconductance as high as 150 μ S μ m − 1 . These results demonstrate
the feasibility of such graphene devices for analogue and radio-frequency circuit applications where bandgap engineering/opening is unnecessary.

而后,组装了顶栅结构石墨烯场效应晶体管,且观察到饱和晶体管特性。饱和速度取决于电荷的载流子浓度,这归因于支撑石墨通道的SiO 2层的界面声子引发的散射。通过一个有效顶栅对通道静电调制获得了150 μSμ m − 1的跨导。这些结果证实了在那些带隙结构工程/打开不必要的模拟和射频电路应用研究中石墨烯器件应用的可行性。
