Pronounced Photovoltaic Response from Multilayered Transition-Metal Dichalcogenides PN-Junctions.


Transition metal dichalcogenides (TMDs) are layered semiconductors with indirect band gaps comparable to Si. These compounds can be grown in large area, while their gap(s) can be tuned by changing their chemical composition or by applying a gate voltage. The experimental evidence collected so far points toward a strong interaction with light, which… (More)
