  • Facile synthesis of tin oxide nanofibres 
    Ahn Jung; Wang Guoxiu; Kim Yong (Elsevier Inc, 2009)
    In this paper, we present a facile method to synthesize SnO2 nanofibres. Unlike the conventional CVD process for synthesizing nanofibres, the present synthesis method needs neither specific source gas nor substrates. Sn¿Ag ...
  • Fano resonances of photonic crystal slabs 
    Byrne Michael; Botten Lindsay; Asatryan Ara; Nicorovici Nicolae; Norton Andrew; Mcphedran Ross; De Sterke C (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    A Bloch mode theory for diffraction of plane waves by planar PC slabs is developed. The theory provides physical insight into the origin of Fano resonances, allowing a simple pole model to be deduced rigorously.
  • FDTDModelling of Dispersive Nonlinear Ring Resonators Accuracy Studies and Experiments 
    Koos Christian; Fujii Masafumi; Poulton Christopher; Steingrueber Ralf; Leuthold Juerg; Freude Wolfgang (IEEE Publications, 2007)
    The accuracy of nonlinear finite-difference time-domain (FDTD) methods is investigated by modeling nonlinear optical interaction in a ring resonator. We have developed a parallelized 3-D FDTD algorithm which incorporates ...
  • Fe in III-V and II-VI semiconductors 
    Malguth Enno; Hoffmann Axel; Phillips Matthew (Wiley - V C H Verlag GmbH & Co. KGaA, 2008)
  • Field profiles for spherical conductive nanoparticles and metallic-shell/dielectric-core nano-composites 
    Schelm Stefan; Smith Geoffrey (Spie-Int Society Optical Engineering, 2004)
    Profiles of the electric field strength |E|2/|Eo|2 for spherical metallic shells on a dielectric core are presented both inside the particle and outside. The dependence of the near-field strength and extent on shell ...
  • Finite element computation of grating scattering matrices and application to photonic crystal band calculations 
    Dossou Kokou; Byrne Michael; Botten Lindsay (Elsevier, 2006)
    We consider the calculation of the band structure and Bloch mode basis of two- dimensional photonic crystals, modelled as stacks of one-dimensional diffraction gratings. The scattering properties of each grating are ...
  • First principles calculations using density matrix divide-and-conquer within the SIESTA methodology 
    Cankurtaran Burak; Ford Michael; Gale Julian (IOP Publishing, 2008)
    The density matrix divide-and-conquer technique for the solution of Kohn¿Sham density functional theory has been implemented within the framework of the SIESTA methodology. Implementation details are provided where the ...
  • First-principles method for high-Q photonic crystal cavity mode calculations 
    Mahmoodian Sahand; Sipe John; Poulton Christopher; Dossou Kokou; Botten Lindsay; Mcphedran Ross; De Sterke C (Optical Society of America, 2012)
    We present a first-principles method to compute radiation properties of ultra-high quality factor photonic crystal cavities. Our Frequency-domain Approach for Radiation (FAR) can compute the far-field radiation pattern and ...
  • First-principles study on the enhancement of lithium storage capacity in boron doped graphene 
    Wang Xianlong; Zeng Zhi; Ahn Hyojun; Wang Guoxiu (American Institute of Physics, 2009)
    The adsorption of Li ions on boron doped graphene was investigated using a first-principles method. Our results show that, as boron doping turns graphene into an electron-deficient system, more Li ions can be captured ...
  • Five layer narrow band position variable filters for sharp colours and ultra low emittance 
    Gentle Angus; Smith Geoffrey (Springer, 2008)
    A simplified approach to creating narrow visible and near IR transmission bands with thin films is outlined utilising just five layers on glass, three of which are thin silver. These films have very high reflection at most ...
  • Folded Bands In Metamaterial Photonic Crystals 
    Chen Pu; Poulton Christopher; Asatryan Ara; Steel Michael; Botten Lindsay; De Sterke C; Mcphedran Ross (Iop Publishing Ltd, 2011)
    The dispersion relation of periodic structures that include metamaterials or materials with large anomalous dispersion can give bands with infinite group velocity points. These bands do not span the entire first Brillouin ...
  • Formation and dissociation of hydrogen-related defect centres in Mg-doped GaN 
    Gelhausen Olaf; Phillips Matthew; Goldys Ewa; Paskova Tanja; Monemar Bo; Strassburg M; Hoffmann Axel (Materials Research Society, 2004)
    Moderately and heavily Mg-doped GaN were studied by a combination of post-growth annealing processes and electron beam irradiation techniques during cathodoluminescence (CL) to elucidate the chemical origin of the ...
  • Formation Of Gold Nanorods By A Stochastic 'Popcorn' Mechanism 
    Edgar Jonathan; Mcdonagh Andrew; Cortie Michael (Amer Chemical Soc, 2012)
    Gold nanorods have significant technological potential and are of broad interest to the nanotechnology community. The discovery of the seeded, wet-chemical synthetic process to produce them may be regarded as a landmark ...
  • Form Birefringence In UVexposed Photosensitive Fibers Computed Using A Higher Order Finite Element Method 
    Belhadj N; Larochelle Sophie; Dossou Kokou (Optical Society of America, 2004)
    The effective index change and form birefringence are calculated in UV-exposed fibers using a high-order vectorial finite element method. The birefringence is compared in optical fibers with and without photosensitive ...
  • Fracture Mechanics Of Mollusc Shells 
    Cortie Michael; Mcbean Katie; Elcombe Margaret (Elsevier Science Bv, 2006)
    The shape and structure of the shells of molluscs has attracted considerable attention. One aspect of interest is the comparatively high resistance to fracture of these shells. It is known that they are composite structures ...
  • Frequency shift of sources embedded in finite two-dimensional photonic clusters 
    Asatryan Ara; Botten Lindsay; Nicorovici Nicolae; Mcphedran Ross; De Sterke C (Taylor & Francis, 2006)
    The frequency (Lamb) shift and local density of states (LDOS) in two-dimensional photonic crystals composed of a cluster of infinitely long circular cylinders is calculated classically using the radiation reaction ...
