我们提出并实验演示了一种功能性电子器件，这是一种使用四端双极性石墨烯场效应晶体管（FET）构建的极性可控逆变器。FET有两个输入端，一个顶栅极和一个后栅极，通过将输入端切换到后栅极，可以切换FET的极性。通过改变后门电压，可以改变逆变器转移曲线的斜率。通过在逆变器的后门和顶门分别加入二进制数字数据和正弦载波，可以构造并运行单晶体管二进制数字相位调制器。
We propose and experimentally demonstrate a functional electron device, which is a polarity-controllable inverter constructed using a four-terminal ambipolar graphene field effect transistor (FET). The FET has two input terminals, both a top gate and a back gate, and the polarity of the FET can be switched by switching the input to the back gate. The slope of the inverter transfer curves can be changed by changing the back-gate voltage. By adding binary digital data and sinusoidal carrier waves into the back gate and the top gate of the inverter, respectively, the one-transistor binary digital phase modulator can be constructed and operated.
