A preparation method and a use of 2D MoSmaterials are provided. Molybdenum source and sulfur powder are used as raw materials, and inert gas is used as carrier gas. Through an intermediate evaporation process, the raw materials are transported to the molten glass surface and deposited into solid molybdenum sulfide. In the subsequent etching-spreading-sulfurization-precipitation process, ultra-high quality and ultra-large area MoSsingle-crystal domains are obtained under normal pressure and without hydrogenation. The single-crystal domain size of the prepared 2D MoSmaterial can reach 1.5 cm, and then grow into a wafer-level 2D MoSmaterial with a size of 2 inches and a thickness of 1-2 layers.

Preparation method and use of two-dimensional MoS2 materials

Provided are a display substrate, a preparation method thereof and a display apparatus. The display substrate includes a substrate, a drive circuit layer disposed on the substrate and a light emitting structure layer disposed on a side of the drive circuit layer away from the substrate, wherein the drive circuit layer includes a transistor, and the light emitting structure layer includes a first electrode, a pixel define layer, an organic light emitting layer and a second electrode, wherein the first electrode is connected with a drain electrode of the transistor, and the organic light emitting layer is located between the first electrode and the second electrode; the pixel define layer includes a plurality of first retaining walls and a plurality of second retaining walls.
