Tungsten disulfide is a typical sandwich layered structure. Because of its relatively weak van der Waals force between layers, it can also be peeled into single or few layers of nanosheets. Tungsten disulfide is considered as another important two-dimensional nanosheet material besides graphene, which has unique physical, chemical and electrical properties.
