Tabletop Fabrication of High-Performance MoS₂ Field-Effect\nTransistors

Abstract

A simple way to prepare\nfield-effect transistors (FETs) using MoS₂ on tabletop\nis presented. Conductive silver paste was applied\nonto chemical vapor deposition (CVD)-grown MoS₂ as Ohmic-contact\nelectrodes. Heating the device in vacuum further enhances the performance\nwithout damage. The final performance is comparable to that of the\nSiO₂-backgated devices prepared by lithography and metal\nevaporators. The role of the silver paste and heat treatment in vacuum\nis investigated by device and spectroscopic analysis.
