Tuning Electron Viscosity with Light

07 Feb 2026 under Highlights

A team of researchers at IISc and NIMS, Japan, has recently developed a technique that enables them to tune the defect density in ultraclean hexagonal boron-nitride-encapsulated graphene devices, thereby controlling the flow of electrons in such devices. This work highlights a pathway to dynamically switch between fluid-like and disorder-dominated transport within the same device. They […]
