Some atomically thin 2D materials can emit customizable light in the color desired when the materials are combined together to create an “artificial semiconductor.” The discovery, made by researchers at the University of Geneva (UNIGE) and the University of Manchester, could spur use of 2D materials on an industrial scale.
Finding new semiconductor materials that emit light is essential for developing a wide range of electronic devices. However, light emission in a semiconductor only occurs when certain conditions are met.
Light emission occurs when an electron jumps inside the semiconductor from a higher to a lower energy level. The color of the emitted light is determined by the difference in energy. For light to…READ MORE
