A photodetector for red and green with balanced negative and positive photocurrent for imaging is realized

Abstract A dual-polarity, photovoltaic photodetector for red-green dual-wavelength detection is demonstrated, operating in the self-powered mode. It is based on a core-shell n-InGaN nanowire/p-Cu2O heterostructure with inner upward energy band bending and near surface downward energy band bending. T...
