Our research is mainly focused on nanotechnology, semiconductor materials and their applications in optoelectronics and electronics at the nanometer scale. Nanomaterials of interest include metal oxides (ZnO, Cu2O, FeO, TiO2, MnO and MoO), metal sulfides (CdS, MoS2), carbon (nanotubes, graphene), chalcogenides (CuInxGa1-xS2, Cu2ZnTnS4), and organic polymers. Optical and electrical properties of the nanostructures are studied for device applications, with special interest in renewable energy (nanowire solar cells, charge storage, and hydrogen generation), photonics, detectors, and bio- and chemical sensors.
