Two-dimensional Tungsten Disilicide Semiconductor Material

Two-dimensional Tungsten Disilicide Semiconductor Material Image

Nanomaterials refer to materials whose dimensions reach the nanometer scale in a certain dimension, two-dimensional or three-dimensional direction. It can be divided into zero-dimensional materials, one-dimensional materials, two-dimensional materials, three-dimensional materials. When a conventional material reaches the nanometer scale, its properties will be very different from usual. When the nanomaterial is a single atomic thickness, it is a two-dimensional material, representative of which is the first published graphene in 2004. In recent years, transition metal two-dimensional materials have also received great attention from scientists, such as tungsten disulfide, molybdenum disulfide or tungsten diselide, which have great potential for the next generation of electronic products.
