Vapor-liquid-solid growth of ZnO nanostructure

In our research we focused on one of methods how to create nanostructure of single crystal of zinc oxide (ZnO). Chosen method was vapor-liquid-solid method. With this method the well aligned wires of single crystal of ZnO can be created on different substrates. In our case we used silicon, sapphire, silica glass and ordinary glass used in laboratory (slide). There are two kinds of morphology of these nanowires. They can be perpendicular to the surface or can have mismatch structure. The ordering strongly depends on the type of substrate — on it crystal system. Perpendicular ones were reached on sapphire substrate, with mismatch structure on silicon and silica glass. No zinc oxide nanowires grown on ordinary glass for laboratory purpose. The length of the wires was from 5 µm to 20 µm. The diameter was from 50 nm to hundreds of nm.
