 This study presents a novel reconfigurable Scotky junction field effect transistor, SJFET, in an asymmetric van der Waals contact geometry. It has demonstrated a balanced and switchable N and P unipolarity with a non-off ratio of over 106. Additionally, it has shown a low leakage current and high rectification ratio. Furthermore, this device can be used as a reversible Scotky rectifier with an ideality factor of 1.0 and a tuned rectifying ratio from 3 by 106 to 2.5x10 to 6. This makes it suitable for use in low-power consumption photovoltaic logic circuits. This article was authored by Yao Chengdu, Lei Tong, Zifeng Chen, and others.
