Transport in disordered monolayer MoS 2 nanoflakes—evidence for inhomogeneous charge transport

We study charge transport in a monolayer MoS 2 nanoflake over a wide range of carrier 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 system up into a series of puddles, rather than previous pictures in which the disorder is treated as homogeneous and uniform. 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.
