III-V NANOWIRES BY SELF-ASSEMBLY MOVPE TECHNOLOGY FOR NOVEL AND EFFICIENT OPTO-ELECTRONIC AND PHOTOVOLTAIC DEVICES

Abstract

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-shellNWs is presented as case study, focusing on the dependence of their structural, optical and electrical properties onMOVPE conditions. MSM diodes fabricated using as-grown core-shell NWs are reported, along with their photoelectricperformances. These devices show potentials for applications as fast photo-detectors and efficient solar cells.
