摘要: Metal-coated oxide nano-aperture arrays have been fabricated using a micro-fabrication technique including stress-dependent oxidation, an isotropic wet etching of silicon oxide, and the metal deposition. Au, Al, Al/Ti double layers deposited on nano-size aperture in order to provide better uniformity coated film ideal shape. The introduction Ti buffer layer reduced surface roughness during reflow process Al deposition resulted circular type
