Mid-infrared distributed-feedback lasing from black phosphorus under nanosecond excitation
Julien Brodeur, Laure Sène, Stéphane Kéna-Cohen
Mid-infrared (MIR) light sources compatible with silicon photonics are highly desirable for environmental sensing and free-space optical communications. Conventional GaSb-based qua…

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…
