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.
