GaN based semi-conductors present numerous advantages linked essentially to their large band gap as compared to traditional Si systems. In addition, it is possible to form hetero-junction III-V HEMTs (High electron Mobility Transistor) like AlGaN/GaN which makes it possible to obtain both a large density of carriers confined at the heterojunction and a high electronic mobility. At the moment these systems are the most promising for high-power hyperfrequency applications. However heating occurs during operation which results in abnormal impacts on the performance of the microelectronic components. Micro-Raman characterization of these components makes it possible to understand the influence of the behaviour of the semi-conductor materials on...
