Sažetak
Direct correlation of structural and optical properties on the nanoscale is essential for rational synthesis of nanomaterials with predefined structure and functionality. We study optical properties of single III−V nitride nanowire radial heterostructures with measured spatial resolution of <20 nm using cathodoluminescence (CL) technique coupled with scanning transmission electron microscopy (STEM). Enhanced carrier recombination in nanowire quantum wells and reduced light emission from regions containing structural defects were directly observed. Using newly developed parallel-detection-mode CL-STEM, we show that optical properties can vary within a single nanowire heterostructure as a function of nanowire morphology.
