MANUFACTURING METHOD OF A GOLD AND SILVER ALLOY NANOWIRE CAPABLE OF MAXIMIZING PLASMON PHENOMENON OF A SURFACE BY CONTROLLING A COMPOSITION RATIO OF THE SILVER AND THE GOLD

摘要

PURPOSE: A manufacturing method of a gold and silver alloy nanowire is provided to manufacture the nanowire which has plasmon property of the surface and high chemical stability by forming the nanowire which has the gold and the silver alloy structure through the vapor phase growth.;CONSTITUTION: A manufacturing method of a gold and silver alloy nanowire comprises the following steps. A gold nanowire is formed on a substrate. A silver vapor is supplied on the gold nanowire. The step of forming a gold nanowire comprises a step of performing an epitaxial growth of the gold nanowire by supplying a gold vapor on the substrate. The substrate is the STO (110) substrate. The gold vapor is supplied as 100-250 sccm of flow rate on the substrate, and the gold nanowire grows to the perpendicular direction about the substrate. The silver vapor is heated to 650-850°C and supplied on the gold nanowire. The manufacturing method of the gold and silver alloy nanowire further includes the following step. The composition of the gold and the silver of the gold and silver alloy nanowire are controlled by adjusting the supplying time of the silver vapor.;COPYRIGHT KIPO 2013
