Twisted van der Waals heterostructures (TVDHs) are two-dimensional materials composed of two or more layers of different two-dimensional materials, such as graphene, transition metal dichalcogenides, hexagonal boron nitride, and black phosphorus, which are stacked together with a relative twist angle. TVDHs have attracted considerable attention due to their unique electronic properties, which are determined by the interlayer interaction and the twist angle. These properties include anisotropic Dirac cones, superconductivity, and valley-polarized photocurrents. TVDHs have potential applications in optoelectronics, valleytronics, spintronics, and quantum computing.
Two-dimensional materials such as Moiré superlattices are a new class of materials with exciting properties that can be used in a variety of applications. The Moiré superlattice is a periodic structure formed by the overlap of two layers of two-dimensional materials, such as graphene, hexagonal boron nitride, transition metal dichalcogenides, and others. By carefully controlling the twist angle between the two layers, the Moiré superlattice can be tuned to host a variety of electronic and optical properties, such as flat bands, highly localized states, and valley-selective optical transitions. These properties make Moiré superlattices attractive for applications in optoelectronics, spintronics, and quantum computing.
Van der Waals heterostructures are two-dimensional materials composed of two or more layers of different materials, such as graphene and hexagonal boron nitride, that are held together by weak van der Waals forces. These forces are much weaker than the covalent bonds that hold atoms together in a single material, but they are still strong enough to keep the layers together. Van der Waals heterostructures have unique electronic, optical, and mechanical properties that make them attractive for a variety of applications, such as optoelectronics, catalysis, and sensors. They are also being explored for use in energy storage and conversion, as well as for use in quantum computing.
