This symposium will bring together people of the growth, characterization and devices physics. It will focus on advances of GaN related materials in aspects such as substrates, epitaxial growth, material processing, characterizations, modeling, in straight forward relation to the realization of laser devices, light emitting diodes, detectors and transistors. Some of the challenges facing the researchers in this area are, the quest for low-defect density growth, low resistive p-doping processes and modern materials characterizations. Special emphasis will be dedicated to investigations that permit to understand the defects which affect the electrical and optical properties of the nitrides. Other issues like the growth of alloys for the infrared, or growth of quantum dots will be also welcome. Physics of quantum wells, modulation-doped heterostructures will be extensively addressed too.
