Abstract:The mid-infrared light-emitting devices are crucial components in free-space optical communication, gas sensing, and military applications. Twodimensional (2D) narrow-bandgap semiconductors offer opportunities for lowcost and tunable miniaturized mid-infrared light sources. Current 2D light-emitting devices face challenges in the effective injection of carriers and complex device structures. In this paper, we report a black phosphorus-based mid-infrared lightemitting diode (LED) with a simple structure of asym… Show more
