Chip-integrated van der Waals PN heterojunction photodetector with low dark current and high responsivity
Abstract
We report a waveguide-integrated BP/MoTe2 PN heterojunction photodetector. It presents ultralow dark currents and high responsivities, which has potentials to develop high-performance on-chip photodetectors for various photonic integrated circuits.
