  • Conduction, storage, and leakage in particle-on-SAM nanocapacitors 
    Zareie Hadi; Ekanayake Sobhath; Cortie Michael; Ford Michael (Institute of Electrical and Electronics Engineers, 2005)
    Individual gold nanoparticles exhibit discrete capacitances of the order of 1 aF, and they can be tethered to a conductive substrate using a bi-functional monolayer of a suitable organic molecule. However the conduction, ...
  • Damping of plasmons of closely coupled sphere chains due to disordered gaps 
    Scheurer Mathias; Arnold Matthew; Setiadi Jeffry; Ford Michael (American Chemical Society, 2012)
    The damping of plasmons due to structural disorder may have important practical consequences. Here, we use spherical harmonic expansions to quantify the damping of plasmons of ensembles of closely coupled sphere chains ...
  • Effect of dipole moment on current-voltage characteristics of single molecules 
    Ford Michael; Hoft Rainer; Cortie Michael (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    We perform empirical calculations of the tunneling current through various small organic molecules sandwiched between gold electrodes by using the Wenzel-Kramers- Brillouin (WKB) approximation. The barrier to tunneling ...
  • Exploring The Performance Of Molecular Rectifiers Limitations And Factors Affecting Molecular Rectification 
    Armstrong Nicholas; Hoft Rainer; Mcdonagh Andrew; Cortie Michael; Ford Michael (American Society of Civil Engineers, 2007)
  • Investigation of the optical properties of hollow aluminium 'nano-caps' 
    Liu Jingquan; Mccredie Geoffrey; Ford Michael; Wieczorek Lech; Cortie Michael (Institute of Physics Publishing, 2005)
    A colloidal suspension of hollow aluminium, cap-shaped nanoparticles (‘nano-caps’) can be conveniently produced by evaporation of aluminium onto a spin-coated layer of polystyrene nanoparticles (PSNPs), followed by ...
  • Laser-induced Assembly Of Gold Nanoparticles Into Colloidal Crystals 
    Harris Nadine; Ford Michael; Cortie Michael; Mcdonagh Andrew (Institute of Physics, 2005)
  • Local electromagnetic fields surrounding gold nano-cap particles 
    Ford Michael; Cankurtaran Burak; Cortie Michael (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    Using the discrete dipole approximation (DDA) the local electromagnetic fields surrounding gold nano-cap particles are investigated. Suitable k-vectors and polarization vectors of the incident light are used to determine ...
  • A new class of self-assembled monolayers on gold using an alkynyl group as linker 
    Ford Michael; Hoft Rainer; Gale Julian; Mcdonagh Andrew (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    The geometry and energetics for adsorption of ethynylbenzene on Au(111) have been studied using Density Functional Theory. The alkynyl group, following removal of the terminal H atom, adsorbs covalently to the surface ...
  • Optimisation of absorption efficiency for varying dielectric spherical nanoparticles 
    Blaber Martin; Harris Nadine; Ford Michael; Cortie Michael (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    In this paper we compare the optical absorption for nanospheres made from a range of transition and alkali metals from Li (A=3) to Au (A=79). Numerical solutions to Mie theory were used to calculate the absorption ...
  • A Plasmon-induced Current Loop In Gold Semi-shells 
    Cortie Michael; Ford Michael (Institute of Physics Publishing, 2007)
  • Quantum electrical characteristic of nanocapacitors 
    Ekanayake Sobhath; Rodanski Benedykt; Cortie Michael; Ford Michael (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2003)
    Current integrated circuit miniaturization will soon require device sizes at atomic scale. Recent work has proposed many Coulomb blockade, and tunneling devices as active devices. However, among passive components, ...
  • Transmitting Hertzian Optical Nanoantenna with Free-Electron Feed 
    Denisyuk A; Adamo Giorgio; Macdonald Kevin; Edgar Jonathan; Arnold Matthew; Myroshnychenko Viktor; Ford Michael; Javier Garcia De Abajo F; Zheludev Nikolay (American Chemical Society, 2010)
    A pair of coupled gold nanorods excited by a beam of free electrons acts as a transmitting Hertzian antenna in the optical part of the spectrum. Significantly enhanced resonant emission is observed from the antenna when ...
