Self-Powered Bipolar Response Photodetector Based on MoS2/SnBi2Te4 Heterojunction.
Self-powered detectors with bipolar photoresponse have significant potential applications across various fields. However, achieving both fast response and high-sensitivity simultaneously in a single bipolar photodetector remains a challenge. In this study, we present a self-powered photodetector based on a MoS2/SnBi2Te...
