Latest Patents

Yihe Liu holds a patent for the "Preparation method and use of two-dimensional MoS2 materials." This patent describes a preparation method that utilizes molybdenum source and sulfur powder as raw materials, with inert gas serving as the carrier gas. The process involves an intermediate evaporation technique that transports the raw materials to a molten glass surface, resulting in the deposition of solid molybdenum sulfide. Through a series of etching, spreading, sulfurization, and precipitation steps, ultra-high quality and ultra-large area MoS2 single-crystal domains are produced under normal pressure and without hydrogenation. The size of the single-crystal domains can reach 1.5 cm, which can then grow into a wafer-level 2D MoS2 material measuring 2 inches in size and 1-2 layers in thickness.
