Visible to Mid-infrared Waveband Photodetector Based on Insulator Capped Asymmetry Black Phosphorous
Processing layer-dependent direct band gap and good absorption coefficient especially in the mid-infrared band, black phosphorous is believed to make a contribution superior to that of graphene in broadband photodetectors. The narrow band gap of 0.3 eV for bulk black phosphorous helps to absorb infr...
