Synthesis and characterization of ZnO nanostructures grown on Si substrates

Artikel i vetenskaplig tidskrift, 2006

ZnO nanostructures were grown by thermal evaporation technique on (001) Si substrate and were characterized by photoluminescence measurements, scanning electron microscope and x-ray measurements. The results show that the formation of ZnO nanostructures is strongly influenced by the growth conditions. By optimizing the growth conditions, orientated ZnO nanorods with a diameter of around 300 nm and lengths of 20-35 μm have been achieved, and they show excellent optical properties. The laser action is observed at room temperature by using optical pumping.
