Experimental evidence for inhomogeneous charge transport in MoS$_{2}$ nanoflakes

ORAL

Abstract

We study electron transport in a monolayer MoS$_{2}$ nanoflake over a wide range of density, temperature, and electric bias. We find that the transport is best described by a percolating picture in which the disorder breaks translational invariance, breaking the MoS$_{2}$ system up into a series of puddles, rather than previous pictures in which the disorder is treated as uniform and homogeneous. Our work provides insight to a unified picture of charge transport in monolayer MoS$_{2}$ nanoflakes and contributes to the development of next-generation MoS$_{2}$-based devices.
