Enhancement of exciton radiative recombination for In-doped ZnO nanowires with aluminum cylindrical micropillars

► We examine the exciton radiative recombination of the ZnO nanowires. ► Al cylindrical micropillars affect the carrier recombination of ZnO/Al structures. ► The interaction of SP resonance between In-doped ZnO nanowire and Al pattern film. ► The carrier transport was responsible for the influences in the optical properties.
