Abstract: A method for forming an array of zinc oxide nanowires on a substrate is disclosed, which includes forming a crystal phase adjusting buffer on the surface of the substrate and growing 1D zinc oxide nanowires on the buffer by zinc vapor deposition, which are normal to the surface of the substrate. The crystal phase adjusting buffer includes, for example, nitride and oxide layers on a silicon substrate, or a gallium nitride epitaxial layer on a sapphire substrate, and is used as a growth buffer layer for the zinc oxide nanowires. The zinc vapor phase deposition includes forming a zinc oxide layer on the crystal phase adjusting buffer and forming vertical zinc oxide nanowires on the zinc oxide layer.

Abstract: The specification discloses a material with a surface nanometer functional structure and the method of manufacturing the same. Using the properties of supercritical fluids, a nanometer structure is formed on the surface of a substrate, resulting in a material with a surface nanometer functional structure. The supercritical fluid carries the precursor of functional materials. Once they reach a reaction balance with the substrate in a high-pressure container, the pressure is released at an appropriate speed. The carbon dioxide supercritical fluid undergoes a vaporization reaction, distributing and adhering the precursors on the substrate to form the surface nanometer functional structure. Utilizing the VLS nanowire growth method, one-dimensional and two-dimensional compound nanometer functional wire structure can be produced.
