We report on the self-assembly by Au-catalyzed metalorganic vapor phase epitaxy (MOVPE) of GaAs-based nanowires (NWs) and their applications to novel and efficient nano-devices. The growth of GaAs and GaAs-AlGaAs core-shell NWs is presented as case study, focusing on the dependence of their structural, optical and electrical properties on MOVPE conditions. MSM diodes fabricated using as-grown core-shell NWs are reported, along with their photoelectric performances. These devices show potentials for applications as fast photo-detectors and efficient solar cells.
