Light momentum turns pure silicon from an indirect to a direct bandgap semiconductor
Credit: ACS Nano (2024). DOI: 10.1021/acsnano.4c02656 UC Irvine-led research reveals that the optical properties of materials can be dramatically enhanced—not by changing the materials themselves, but by giving the light new properties. The researchers demonstrated that by manipulating the momentum of incoming photons, they could fundamentally change how light interacts with matter. One striking example
