Systematic investigation of the mechanical, electronic, and interfacial properties of high mobility monolayer InAs from first-principles calculations

Abstract

C and ML graphene). 2D InAs was metallized after contact with the seven bulk metals and two 2D metals. Based on the above, we insert 2D boron nitride (BN) between ML InAsH and the seven low/high-power function bulk metals to eliminate the interfacial states. Remarkably, the semiconducting properties of 2D InAs with Pd and Pt electrodes are recovered, and 2D InAs achieves p-type ohmic contact with the Pt electrode, which facilitates high on-current and high-frequency operation of the transistor. Hence, this work provides systematic theoretical guidance for the design of next-generation electronic devices.
