OECD category: Condensed matter physics (including formerly solid state physics, supercond.)

In this paper is demonstrated the effective deposition concept of sequential (cyclic) sputtering of Au nanoisland arrays (NIA) with Ti ultrathin non-continuous film (as supplemental intermediate “seeds” for Au growth) on Corning glass substrates. The morphology of Au/Ti NIA was investigated by scanning electron microscopy and crystalline structure was analysed by X-ray diffraction. Optical properties were evaluated by transmission UV-Vis spectroscopy: the transverse localized surface plasmonic resonance of Au/Ti NIA, the extinction peak intensity/width and the plasmon resonance wavelength shift were dependent on Au nominal thicknesses. Sputtering of the Ti intermediate ultrathin film between the glass substrate and gold improves the crystalline texture and the adhesion of Au NIA as well as supporting the formation of more defined Au NIA structures.
