Liu Sheng and the Rise of Layered Material Physics

Definition and Overview of Layered Materials Layered materials are a class of substances characterized by their two-dimensional (2D) atomic arrangements, where individual layers are stacked and held together by weak van der Waals forces. This unique structural feature allows for remarkable tunability in their physical and chemical properties, making them a focal point in modern […]
