Complementary Logic with Voltage Zero‐Loss and Nano‐Watt Power via Configurable MoS2/WSe2 Gate

Abstract

AbstractDue to the development of 2D material transistors research and preparation process, many fundamental logic units, like inverter and NAND gate, have been achieved to promote large‐scale integration. However, there are critical challenges like voltage loss and large dynamic power consumption for integrated circuits based on 2D semiconductors. Here high‐performance logic devices via different MoS2‐WSe2 configurations, a MoS2‐WSe2 complementary logic transmission gate with the ability to transport electrical level without any voltage loss and a MoS2‐WSe2 complementary logic inverter with small dynamic power consumption and maximum voltage gain of 18 are demonstrated. Furthermore, an essential logic unit like Schmidt flip‐flop is put forward by combining MoS2‐WSe2 inverter and graphene floating gate. The realization of various logics achieved by different MoS2‐WSe2 configurations makes it much easier to fabricate multifunctional system on a chip, which has a significant meaning for the development of high density integrated circuits.
