Current Crowding in a High-Efficiency Black Phosphorus Light-Emitting Diode Using a Reflective Back Contact
Julien Brodeur, Éloïse Rahier, Mathieu Chartray-Pronovost +3
We demonstrate a high-performance mid-infrared (MIR) light-emitting diode (LED) based on a black phosphorus (b-P)/n-MoS heterojunction. A gold back contact combined with a rhen…
