The Crystal Structure of Bubbles in the Wet Foam Limit (Amendment)
(Royal Society of Chemistry, 2006)We have observed a rich variety of three-dimensional crystal and defect structures spontaneously formed by small (diameter 200 mm) bubbles in a wet foam. The observations confirm and extend those made by Bragg and Nye ... -
Experimental investigation of polarisation rotation in semiconductor optical amplifiers
(IEEE, 2004)An experimental study of polarisation rotation in a semiconductor optical amplifier is presented. Two techniques are used to investigate the gain and birefringence along the two eigenmodes of the component waveguide, with ... -
Magnetic, magnetotransport, and optical properties of Al-doped Zn0.95Co0.05O thin films
(American Institute of Physics, 2007)Thin films of 5% Co-doped ZnO with a range of Al codoping exhibit a band-edge shift, which varies with carrier concentration as n2/3. Carrier effective mass is 0.26me and mobility is ~ 10?cm2?V?1?s?1. The doped films, which ... -
Novel Pre-oxidation Patterning on Thin Aluminium Film Generating Ordered Nanopores through Anodization
(2010)Anodic Aluminum Oxide (AAO) is widely employed as a template for fabrication of nanowires and nanotubes due to its ability to generate self organized (SO), well ordered pore structures. We have developed a new aluminum ... -
Size-dependent scaling of perpendicular exchange bias in magnetic nanostructures
(American Physical Society, 2007)Size-dependent scaling is studied in exchange biased nanostructures obtained by depositing Pt/Co 3 /IrMn multilayers with perpendicular magnetization onto an array of monodisperse polystyrene nanospheres with a diameter ... -
The two-dimensional viscous froth model for foam dynamics
(American Physical Society, 2004)The two-dimensional viscous froth model is a simple tractable model for foam rheology and coarsening. It includes, but is not confined to, the quasistatic regime. Here we present a detailed analysis and implementation of ...
