Manipulation of The Electronic Transport Behavior in Monolayer Semiconductors with Dielectric Screening

ORAL

Abstract

By virtue of their atomic-level thinness, the properties of layered 2D semiconductors and their heterostructures can differ substantially from their 3D counterparts. For instance, electronic properties of a monolayer semiconductor can be strongly influenced by the surrounding dielectric environment. We study the implications of the dielectric screening phenomenon in monolayer MoS2 by using electrical transport and scanning probe microscopy measurements. The possibility to tailor the electronic band properties of 2D semiconductors by using dielectric environment provides an alternative route to realize new electronic and optoelectronic device concepts.
