Indirect to direct band gap crossover in two-dimensional WS2(1−x)Se2x alloys

Abstract In atomically thin transition metal dichalcogenide semiconductors, there is a crossover from indirect to direct band gap as the thickness drops to one monolayer, which comes with a fast increase of the photoluminescence signal. Here, we show that for different alloy compositions of WS2(1−x)...
