Abstract

2D semiconductors, including transition metal dichalcogenides (TMDs), have been widely studied recently. However, the device performance is deteriorated due to the significant contact resistance. The contact resistance of MoS₂-metal contacts decreases with the thickness of MoS₂. We obtained a Schottky barrier height as low as about 70 meV when MoS₂ is trilayer-thick. It is important to find the optimal choice of contact metal and layer thickness of MoS₂.
