摘要: Zinc oxide nanopillars were grown by a self-catalyzed growth process on an epitaxial Ir/yttria-stabilized zirconia/Si(111) multilayer structure in optically heated tube furnace. The pillars obtained stand upright parallel to each other with their c-axis perpendicular the sample surface. Problems due alloying of Zn Si are completely avoided, and no irregularities initial phase found. Cathodoluminescence measurements show narrow linewidths below 700μeV excellent crystal quality. Termination ZnO flat metallic iridium layer is attractive issue towards optical cavity for laser action.
