摘要

我们设计和制造了高速柔性石墨烯场效应晶体管(gfet)，具有高电子迁移率(~8000cm2/V.s)，空穴迁移率(~ 6600cm2/V.s)和记录的固有传输频率- ft为~32GHz。我们还设计和制造了第一个基于柔性石墨烯的调幅(AM)无线电接收机，工作频率为2.4GHz。该无线电包括一个基于GFET的解调器和柔性石墨微带贴片天线，谐振频率为2.4GHz。

Towards the design and fabrication of graphene based flexible GHz radio receiver systems

We present the design and fabrication of high speed flexible graphene field effect transistors (GFETs) with high electron mobilities (~8000cm2/V.s), hole mobilities (~ 6600cm2/V.s) and record intrinsic transit frequency-fT of ~32GHz. We also present the design and fabrication of the first flexible graphene based amplitude modulated (AM) radio receiver operating at 2.4GHz. This radio includes a GFET based demodulator and flexible graphite microstrip patch antenna resonating at 2.4GHz.
