We report a determination of the complex in-plane dielectric function of monolayers of four
transition-metal dichalcogenides: Mo S 2, Mo S e 2, WS 2, and WS e 2, for photon energies …

Two-dimensional group-VI transition metal dichalcogenide semiconductors, such as MoS2,
WSe2, and others, exhibit strong light-matter coupling and possess direct band gaps in the …

The discovery of graphene has ignited intensive interest in two-dimensional layered
materials (2DLMs). These 2DLMs represent a new class of nearly ideal 2D material systems …

We realized photovoltaic operation in large-scale MoS2 monolayers by the formation of a
type-II heterojunction with p-Si. The MoS2 monolayer introduces a built-in electric field near …
