High Performance Phototransistor Based on 0D-CsPbBr₃/2D-MoS₂ Heterostructure with Gate Tunable Photo-Response.

ABSTRACT: Monolayer MoS₂ has been widely researched in high performance phototransistors for its high carrier mobility and strong photoelectric conversion ability. However, some defects in MoS₂, such as vacancies or impurities, provide more possibilities for carrier recombination; thus, restricting the formation of photocurrents and resulting in decreased responsiveness. Herein, all-inorganic CsPbBr₃ perovskite quantum dots (QDs) with high photoelectric conversion efficiency and light absorption coefficients are introduced to enhance the responsivity of a 2D MoS₂ phototransistor. The CsPbBr₃/MoS₂ heterostructure has a type II energy band, and it has a high responsivity of ~1790 A/W and enhanced detectivity of ~2.4 × 10¹¹ Jo
