Figures 1a and 1b below show the nanowires made by CRHEA by EJM with ammonia source as well as by MOCVD, in self-organized growth mode. In the interest of a better homogeneity and a better control of their positioning, the localized growth of nanowires on dielectric mask was then developed by MOCVD, as shown in Figures 1 (c), (d), (e) and F). The optimization of the nanowires manufacturing process as well as the study of their structural and optical properties were the subject of a first thesis defended in 2014 by Pierre-Marie Coulon. Another thesis in progress is devoted to the realization of an electrically injected polariton laser based on GaN microfilts, within the framework of the LABEX GANEX.
