The core of our research is the study of the physical properties of single and complex nanostructures based on semiconductor oxides and nanocomposites: binary oxides (Ga₂O₃, TiO₂, SnO₂, NiO, CuO, Sb₂O₃, MoO₃ …), ternary compounds (Zn₂GeO₄, IZO, stannates, beta-galia rutile) and nanocomposites with reduced graphene oxide or several polymers. By doping / morphology / defects engineering we pursue improvement in performance of devices with applications in optoelectronics, solar cells, batteries or sensors. Recenlty, we focus on exploiting the mixing dimensionality effects of the nanostrutures (nanomembranes and nanowires) in their physical properties.
