Due to the action of light, pure silicon changes from an indirect bandgap semiconductor to a direct bandgap semiconductor.
Credit: ACS Nano (2024). DOI: 10.1021/acsnano.4c02656 Research led by the University of California, Irvine has found that the optical properties of materials can be dramatically improved by imparting new properties to light, rather than changing the material itself. The researchers have demonstrated that by manipulating the momentum of incoming photons, they can fundamentally change the way light interacts with matter.…
