Scientific Research is an amazing mix of both collaborative and competitive research. Finding the correct balance of the two is the crucial aim, and permanent goal, for any laboratory. By focusing the activity of CRHEA upon epitaxial growth, it is, and has been, our strategy to develop a world class expertise in the field of compound semiconductors and to be competitive in the current and future scientific community. Through the development of a large number of industrial and academic collaborations, involved in physics, optics and optoelectronic devices we have now firmly established our place within this community. As a result the research performed at CRHEA has at very least a national, but very often an international dimension.

The modern world is based on ever changing and fast developing technology. Numerous innovations of science and technology affect our everyday life. To comprehend the potential of modern technology and to achieve the even greater goal of embracing such technology, much of which could even not dreamed of some decades ago, has become commonplace in modern society due to the huge strides undertaken by the scientific community as a whole. Nowadays the huge progress made in every field of science seems to come as no surprise to anyone, and such progress seems simply to be expected. What is often not appreciated, regarding the huge steps in science and technology, is that every step forward becomes evermore challenging and increasingly expensive. Progress in science and technology obviously requires excellence in research. However more and more the excellence of individual laboratories, and indeed nations is simply not enough. A collaborative effort at both a national and international level is becoming an increasing necessity. In the modern scientific community real progress is predominately made through the focused research of a number of partners in specific fields of excellence. It is such national and international collaborative research that has been chosen by CRHEA to develop its future goals within the scientific community. The epitaxial growth of compound semiconductors is a huge field of research. As such CRHEA has chosen to focus its research predominantly upon the wide band gap semiconductors such as the group III-Nitrides, SiC and ZnO. This philosophy has allowed CRHEA to develop mutually beneficial collaborations with a number of industrial partners including ST Microelectronics, THALES, RIBER, NOVASIC, Saint Gobain. It has also led to the recent ‘spin-off’ of a start-up company LUMILOG. Through expertise directly developed at CRHEA, LUMILOG now produce and sell industrial standard GaN templates and substrates. Last but not least, the focus of our research on the wide band gap semiconductors allows CRHEA to enter into numerous national and European projects. The international role of CRHEA is further evidenced by the numerous scientists from around the world who have, and continue to, work at CRHEA.
At CRHEA education is also a major priority. There are numerous students currently undertaking their PhD at CRHEA, while a number of the scientists at CRHEA have academic roles at the University of Nice Sophia Antipolis.
CRHEA is a CNRS laboratory, amalgamated to the Physics Institute INP (UPR10), with strong links with the Information and Ingeniery Science and Technology Institute INST2I. It is managed by the Délégation Régionale 20.
