Breakdown of the future prospects of crystal electric storm UV LED

The day before, EPISTAR joint Taiwan y-key center, and the Centre College film technology center, the manufacturing technology of advanced materials, graphene used in UV-LED, UV-LED are expected to enhance the level of manufacturing technology, and to the United States and Japan manufacturers racing together bridle to bridle state, estimate the annual output value of more than 360 million new Taiwan dollars (about 73 million 70 thousand yuan).

UV-LED can be used in agriculture, bill recognition, resin hardening, special biomedical and other fields, the market prospects, but the current high power UV-LED using indium tin oxide (ITO) as a transparent conductive film, will happen to bad heat and current distribution uneven, affecting its luminous efficiency.

Y-key center crystal electric and Centre College, Ministry of science and technology development and technology made in Central Taiwan Science Park Administration plans to support high-tech equipment, joint implementation of "the development of application of high temperature plasma assisted atomic layer deposition system in the UV-LED program, which is more suitable for transparent electrode material graphene using LED (graphene) to replace indium tin oxide, hope to overcome the problem of low luminous efficiency UV-LED.

The key technologies of this research are two, one is to make the low temperature process (about 600 degrees C) graphene can be directly generated on the platinum film, in order to make electrodes. Centre College film technology center Professor Li Zhengzhong, assistant professor Guo Qiancheng team responsible for the development of graphene low temperature process, Instrument Science Center is responsible for make graphene directly generated in the platinum film (this is called "high temperature plasma assisted atomic layer deposition system").

The second key technique is to make the electrode and the light-emitting layer can be combined with the perfect LED, this part by y-key EPISTAR joint research and development center and.

This cooperation will initially test and verification on the Jingguang, until the technology is mature, the principal instrument science center and Centre College Film Technology Center for technology transfer to equipment manufacturers, related equipment manufacturing.
