Scientists Discover Process That Enables Low-Power Nanolasers in 2D Semi-Materials

Scientists at Arizona State University (ASU) have identified the process in physics that enables nanolasers to be created using 2D materials. This led them to the discovery of a mechanism for providing optical gain in 2D materials at much lower density levels than traditional semiconductors. The research could provide an alternative to conventional semiconductors and could be game-changing for energy-efficient photonic devices. In 2017, professor Cun-Zheng Ning and his collaborators at Tsinghua University produced experimental results showing that lasers could be produced in 2D materials as thin as a single layer of molecules. While other researchers had developed these lasers at cryogenic temperatures, Ning’s team produced...
