Overcoming the Dark Current–Spectral Range Trade‐Off in Room‐Temperature Two‐Dimensional Photodetectors via Photothermal‐Assisted Tunneling

ABSTRACT The intrinsic trade‐off between low dark current and broadband detection fundamentally limits the performance improvement of 2D photodetectors. Here, we report a MoTe 2 /h‐BN/graphene tunneling heterostructure photodetector that synergistically integrates the high insula...
