The CEA-CNRS-UJF joint “nanophysics and semiconductors” group studies the vapor phase growth of GaN-based nanostructures, including InGaN heterostructures. By understanding the growth mechanisms, we can obtain original structures such as wires or pyramids. Their practical interest is demonstrated in emitters and photodetectors.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
