Correlating Luminescence from Individual ZnO Nanostructures with Electronic Transport Characteristics

Cathodoluminescence (CL) emissions from individual ZnO nanostructures with diameters of 30−100 nm are investigated to correlate their optical and electrical properties. Two types of ZnO nanostructures with high and low charge carrier densities are identified from electronic transport measurements an...

Zusammenfassung:Cathodoluminescence (CL) emissions from individual ZnO nanostructures with diameters of 30−100 nm are investigated to correlate their optical and electrical properties. Two types of ZnO nanostructures with high and low charge carrier densities are identified from electronic transport measurements and concomitant CL characterizations. The results demonstrate that local luminescence characterizations can provide information about inhomogeneities in electrical and optical properties among ZnO nanostructures.
