摘要
En 中文
In this study, we propose doping-less feedback field-effect transistors (DLFBFETs). Our DLFBFETs are 5 nm thick intrinsic semiconductor bodies with dual gates. Usually, DLFBFETs are virtually doped through charge plasma phenomena caused by the source, the drain, and the dual-gate electrodes as well as the gate biases. Our DLFBFETs can be fabricated through a simple process of creating contact between a metal and a silicon body without any doping processes. The voltages applied to both gates determine whether the DLFBFETs operate in diode or feedback field-effect transistor (FBFET) modes. In the FBFET mode, our DLFBFETs show good characteristics such as an on/off current ratio of similar to 10(4) and steep switching characteristics (similar to 1 mV/decade of current) that result from positive feedback phenomena without dopants.
