Scientists create an “electron lighthouse” with laser light

Researchers at the University of Michigan have made a groundbreaking semiconductor device that directs electron movement using laser light, without needing an electric field. This innovative approach could revolutionize technologies in optics and electronics, paving the way for advanced sensing and telecommunications. By using two colors of light, they can control the flow and direction of electrons, much like a lighthouse beam. It's a fascinating leap from traditional methods, showcasing the power of quantum interference in a practical application.
