The combination of top-down and bottom-up approaches makes it possible to exploit all the possibilities offered by nanostructures and this is the strength of the Nanotechnologies team, which uses GaN and ZnO as materials of choice. Our interests range from basic materials science, including MBE and MOCVD growth to new materials (eg ZnMnO, rare earth nitrides and oxynitrides), to the development of more complex nanophotonic systems. These include metasurfaceswhich allow the manufacture of ultrathin-ultralight optoelectronic components such as metal lenses, optical microcavities. These are the ideal playground for testing effects in quantum electrodynamics and obtaining Bose-Einstein condensates in a semiconductor environment. Finally, a last nanophotonic platform based on GaN nanowires is able to stimulate biological cells with unprecedented spatial resolution. Moreover, the manipulation of the spin of carriers and / or excitons within these photonic structures, thanks to our magnetic materials, opens the possibility of coupling spin and photons in an electrically addressable interface.
