III-V semiconductor integration on a Si platform constitutes a major challenge for the coming years in the world of microelectronics. These materials, by their direct bandgap, offer the possibility of realizing light emission ranging from visible to infrared (ultra-violet for III-N). These components are currently produced by epitaxy on GaAs, InP or GaSb substrates. A more exploratory path consists in growing the structure of interest directly on the silicon substrate, which has, among other things, the advantage of eliminating the III-V substrate and of working directly on Si CMOS compatible substrates. Moreother, elements of column III and V being considered to be critical (Sb, P, In, Ga in particular), this also makes it possible to limit their consumption.
In this context, the objective is to set up a III-V semiconductor integration path to produce optoelectronic devices, such as PIN diodes. The candidate will focus on developing all the technological processes necessary for the production and characterization of functional devices.
