The Chemistry Of Two-dimensional Layered Transition Metal Dichalcogenide Nanosheets

Synthesis of large quantities of single or few-layer-thick 2-D materials is crucial to understanding the true commercial potential of materials such as transition metal dichalcogenides. January 29).

These two dimensional (2D) transition metal oxides (TMOs – for brevity we use the term transition for all discussed metals) can appear as single planar structures, multi layer of individual TMOs or multi layer and superlattice configurations of different TMOs.

A layer structure may include a carrier, a two-dimensional layer, and a holding structure. The holding structure is arranged on the carrier and holds the two-dimensional layer on the carrier such that at least a portion of the two-dimensional layer is spaced apart from the carrier. The holding structure includes a holding portion extending from the two-dimensional layer towards the carrier.

The scientists controlled the synthesis of a transistor in which narrow channels were etched onto conducting graphene, and a semiconducting material called a transition-metal dichalcogenide.

The amazing properties of this two-dimensional (2D) material have prompted research on other 2D layered materials, of which layered transition metal dichalcogenides (TMDCs) are important members. Single-layer and few-layer TMDCs have been synthesized and characterized.
