High-sensitivity, high-speed, broadband mid-infrared photodetector enabled by a van der Waals heterostructure with a vertical transport channel by Jianfeng Wu, Jialin Zhang, Ruiqi Jiang, Hao Wu, Shouheng Chen, Xinlei Zhang, Wenhui Wang, Yuanfang Yu, Qiang Fu, Rui Lin, Yueying Cui, Tao Zhou, Zhenliang Hu, Dongyang Wan, Xiaolong Chen, Weida Hu, Hongwei Liu, Junpeng Lu, Zhenhua Ni

“…Two-dimensional (2D) heterostructures provide an alternative path toward this goal, yet despite continued efforts, their performance has not matched that of low-temperature HgCdTe photodetectors. Here, we push the detectivity and response speed of a 2D heterostructure-based mid-infrared photodetector to be comparable to, and even superior to, commercial cooled HgCdTe photodetectors by utilizing a vertical transport channel (graphene/black phosphorus/molybdenum disulfide/graphene). …”
