Title: Synthesis, modeling and applications of III-V nanowires and nanowire heterostructures: Opportunities and challenges

Abstract

We will review the state-of-the art research in the field of synthesis and modeling of III-V semiconductor nanowires (NWs) and photonic nano-heterostructures based on such NWs. Some recent advancements will be discussed, including coherent growth in regular arrays on silicon substrates and some growth features of the vapor-liquid-solid growth which enable controllable tuning of the NW morphology, composition, crystal phase and statistical properties of the size distributions within the ensembles of NWs. Opportunities and challenges for optoelectronic applications of III-V NW heterostructures will be discussed, including single photon generation.
