Scalable, Simple, and Versatile Encapsulation of 2D Materials and Devices

Abstract Air-sensitive 2D materials present fundamental challenges for device integration. Encapsulation is required to preserve intrinsic properties, yet conventional strategies require complicated fabrication workflows and fail with thicker flakes. We demonstrate that electron-...

Light-controlled van der Waals tunnel junctions: Mechanisms, architectures, functionalities, and opportunities

The phenomenon of electron tunneling has long been central to quantum transport and continues to provide a powerful framework for understanding and controlling electronic processes in solids. When combined with optical excitation, tunneling becomes a particularly rich platform fo...
