Researchers at SLAC discovered light-twisting behavior in ultrathin tungsten ditelluride film, enabling potential applications in optoelectronic devices.

Researchers at SLAC National Acceleratory Laboratory discovered new light-twisting behavior in ultrathin tungsten ditelluride film using a high-speed electron camera. When oriented in a specific direction and subjected to linear terahertz radiation, the ultrathin film circularly polarizes incoming light, offering potential for optoelectronic devices, such as LEDs, optical fibers, and medical imaging.
