  • Controlled in situ growth of tunable plasmonic self-assembled nanoparticle arrays 

    FLEISCHER, KARSTEN; MC GILP, JOHN FINLAY; SHVETS, IGOR; FOX, DANIEL (2012)
    Self-assembled silver nanoparticle (NP) arrays were produced by deposition at glancing angles on transparent stepped Al2O3 templates. The evolution of the plasmonic resonances has been monitored using reflection anisotropy ...
  • Equilibrium faceting formation in vicinal Al2O3 (0001) surface caused by annealing 

    FOX, DANIEL; SHVETS, IGOR; FLEISCHER, KARSTEN; ZHANG, HONGZHOU; USOV, VICTOR; VERRE, RUGGERO; SOFIN, SUMESH; BEHAN, G. (Elsevier B.V., 2012-07)
    We report on a heat-induced transformation of the surface of ?-alumina (0001) crystals which have an off-cut in the [1-210] direction. Annealing the crystal causes the surface to transform into a regular array of (0001) ...
  • General approach to the analysis of plasmonic structures using spectroscopic ellipsometry 

    ZHANG, HONGZHOU; SHVETS, IGOR; SMITH, CHRISTOPHER MICHAEL; MC GILP, JOHN FINLAY; FOX, DANIEL; FLEISCHER, KARSTEN (2013)
    In this article a route to analyze the full optical response of plasmonic structures is developed. First, the simple case of an anisotropic thin plasmonic layer supported on a transparent substrate is analyzed by ...
  • Nitrogen assisted etching of graphene layers in a scanning electron microscope 

    O'NEILL, ARLENE; FOX, DANIEL; ZHANG, HONGZHOU; COLEMAN, JONATHAN NESBIT (2011)
    We describe the controlled patterning of nanopores in graphene layers by using the low-energy (<10?keV) focused electron beam in a scanning electron microscope. Regular nanometer-sized holes can be fabricated with the ...
