Broken-Gap PtS₂/WSe₂ van der Waals Heterojunction with Ultrahigh Reverse Rectification and Fast Photoresponse

Jones. In addition, the response time of such a photodetector reaches 8 μs owing to the photoinduced tunneling mechanism and reduced interface trapping effect. The proposed heterojunction not only demonstrates the high-performance broken-gap heterodiode but also provides in-depth understanding of the tunneling mechanism in the development of future electronic and optoelectronic applications.
