Low-Noise Mid-Infrared Photodetection in BP/h-BN/Graphene van der Waals Heterojunctions
We present a low-noise photodetector based on van der Waals stacked black phosphorus (BP)/boron nitride (h-BN)/graphene tunneling junctions. h-BN acts as a tunneling barrier that significantly blocks dark current fluctuations induced by shallow trap centers in BP. The device provides a high photodet...
