New progress in the study of epitaxial deep ultraviolet LEDs on graphene

Deep ultraviolet LEDs can be widely used in the fields of antivirus, sterilization, printing and communication. Recently, the Lighting Research and Development Center of the Institute of Semiconductors of the Chinese Academy of Sciences, in collaboration with the Nanochemistry Research Center of Peking University and the Liu Zhongfan team of the Beijing Graphene Research Institute, developed a new epitaxial substrate of graphene/sapphire and proposed plasma pretreatment modified graphene. A new strategy to promote the growth of AlN films to achieve deep UV LEDs.

At the same time, Wei Tongbo and Liu Zhongfan teamed up to propose a growth model of graphene/NPSS nano-patterned substrate epitaxial AlN, which makes the deep ultraviolet light source a potential breakthrough for graphene industrialization.
