Latest Patents

Hwang holds a patent titled "Method for synthesis of high quality graphene." This patent describes a thermal process for producing high-quality graphene layers on silicon carbide wafers. The method involves two wafers placed in close proximity, where a vacuum heating stage is employed. During this stage, the temperature is raised to approximately 1500°C, causing silicon to evaporate from the wafer and leaving a carbon-rich surface. The evaporated silicon is trapped in the gap between the wafers, which helps suppress further silicon evaporation. As the temperature increases to about 1530°C or more, the carbon atoms self-assemble into graphene. Hwang's innovative approach has led to the development of a method that could enhance the quality and efficiency of graphene production.
