Actively variable-spectrum optoelectronics with black phosphorus

Nima Azar, Sivacarendran Balendhran and Ken Crozier are co-authors on a Nature paper with colleagues from the University of California at Berkeley and the Lawrence Berkeley National Lab. They made use of the extraordinary sensitivity of the bandgap of black phosphorous (bP) to strain to show the continuous and reversible tuning of the operating wavelengths in bP light-emitting diodes and photodetectors.
