A ternary SnS_1.26Se_0.76 alloy for flexible broadband photodetectors.

ABSTRACT: Layered two-dimensional (2D) materials often display unique functionalities for flexible 2D optoelectronic device applications involving natural flexibility and tunable bandgap by bandgap engineering. Composition manipulation by alloying of these 2D materials represents an effective way in fulfilling bandgap engineering, which is particularly true for SnS_2x Se_2(1-x) alloys showing a continuous bandgap modulation from 2.1 eV for SnS₂ to 1.0 eV for SnSe₂. Here, we report that a ternary SnS_1.26Se_0.76 alloy nanosheet can serve as an efficient flexible photodetector, possessing excellent mechanical durability, reproducibility, and high photosensitivity. The photodetectors show a broad spectrum detection ranging from
