- Abstract
ZnO nanorods arrays on ZnO buffered Si substrates have been obtained by conventional chemical vapor deposition. The influence of ZnO buffer layer on the growth and properties of the ZnO nanorods have been studied. The morphology and the alignment ordering of ZnO nanorods arrays were greatly affected by the thickness of ZnO buffers. Photoluminescence and field emission properties can be enhanced by modulating the thicknesses of the ZnO buffer layers. ZnO nanorods with the best crystallinity and the highest ordering were obtained with 50-nm-thick ZnO buffer layer, which exhibits the strongest UV emission.
