European Union researchers, who were involved in project GECCO have for the first time created a '3D nano-LED' for white light, will see their work continued under the cooperation with Germany's Epitaxy Competence Center - ec.

Following the end of the funded GECCO project which investigated 3D GaN for high efficiency solid state lighting applications ec, which was opened by Osram Opto Semiconductors and Germany's Institute of Semiconductor Technology, Technical University of Braunschweig, will extend the development work for industry.

The ec has been established as a two million euro joint venture between the Lower Saxony Ministry of Science and Culture, Braunschweig University of Technology and Osram Opto Semiconductors GmbH. The Center's main focus is on GaN technology, which underpins potential applications in optoelectronics, LED and laser technologies as well as power electronics and sensors.

All of these technologies are essential building blocks for the automotive industry, the field of mechanical engineering, as well as medical and other application areas.

ec, which was formed as a Gallium Nitride Research Center to increase the importance of the gallium nitride technology (GaN) in Germany, is focusing on stimulating the evolution of epitaxy production methods in Germany while also providing the infrastructure for nano-analysis and processing techniques. The ec builds a bridge between basic research at universities on the one hand and product-oriented research and development in the industry on the other.

GaN-based white LED technology are being designed into car headlights as as as LED lamps and streetlighting.

"GaN-based white LED technology will continue to gain market share," said Aldo Kamper, CEO of Osram Opto Semiconductors, in his speech at the opening ceremony. At the same time efficient processes are always asked: "Technological development towards even greater performance and lower cost of production has to go faster. This only works if industry and academia work together closely; in research projects or with ec as a center of excellence. In addition, the employees of such centers combine enormous expertise and form a pool of talent in the field of semiconductor technology".

"In the future we plan to expand epitaxy further and further develop the infrastructure for nano-analysis and systematic processing," explained Dr.-Ing. Snke Fndling, head of ec, further plans for the center of excellence.
