We focus on the study of the physical properties of single and complex nanostructures, involving nanoparticles, nanowires and nanomebranes, based on semiconductor oxides. By doping / morphology / defects engineering we pursue improvement in performance of devices with applications in optoelectronics, solar cells, batteries or sensors.
