Researchers report controllable nonlinear hall effect in twisted bilayer graphene

A team of international researchers, led by The University of Hong Kong (HKU) and The University of Science and Technology (HKUST), recently made a discovery in the field of quantum materials, uncovering the controllable nonlinear Hall effect in twisted bilayer graphene. The findings shed new light on the unique properties of two-dimensional quantum moiré materials and hold promise for a wide range of applications in industries such as new materials and quantum information to achieve terahertz detection with ultra-high sensitivity at room temperature.
