In this study, we report the growth of core–shell GaAsP nanowires using metal–organic chemical vapor deposition. The grown core–shell nanowires were examined by detailed electron microscopy, revealing that the P concentration in the nanowire cores is higher than that in the shells. Au catalysts enhanced the local decomposition of PH₃, leading to relevant high P incorporation in the nanowire cores during nanowire growth. These core–shell GaAsP nanowires exhibit enhanced electrical...[Show more]
