A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin have found out that a semiconductor can be converted to a metal and back by light more easily and more quickly than previously thought. This discovery may increase the processing speed and simplify the design of many common technological devices.

Much of the technology used today relies on transistors. They connect many of the materials that make up these devices, and are essential for any kind of data processing. Because transistors are so important, scientists and engineers have long tried to optimize them by modifying their so that they can be used more flexibly. Now, a team of researchers the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin has found an important clue on how to achieve that.
