Photodetectors: Fast, Self‐Driven, Air‐Stable, and Broadband Photodetector Based on Vertically Aligned PtSe₂/GaAs Heterojunction (Adv. Funct. Mater. 16/2018)

Abstract

Group-10 transition metal dichalcogenides like PtSe2 have been widely highlighted for various potential applications. In article number 1705970, Lin-Bao Luo, Yuen Hong Tsang and co-workers synthesize large-area, high-quality and vertically aligned PtSe2 films through a simple selenization method. Optoelectronic characterization reveals that PtSe2-GaAs heterojunctions exhibit high responsivity, fast response speed, and broadband sensitivity to illumination ranging from deep ultraviolet to near infrared light.
