  • Surface studies of magnetite (100) 

    Seoighe, Ciaran (Trinity College (Dublin, Ireland). School of Physics, 2000)
    The (100) surface of magnetite (Fe3 O4 ) has been studied using scanning tunneling microscopy (STM) in ultra high vacuum (UHV) with a view to establishing a test surface for spin polarised STM experiments. Two structured surface ...
  • A search for X-ray flares in the nuclei of galaxies 

    Cunniffe, John (Trinity College (Dublin, Ireland). School of Physics, 2003)
    Observations of the giant elliptical galaxy NCG 4552 at ultraviolet wavelengths during the early 1990’s showed sharply peaked emission within ~2pc of its centre which initially brightened and then faded. The features of ...
  • Ultrafast non-linear optics for telecommunication applications 

    Communal, Jean-Edouard Paul Camille (Trinity College (Dublin, Ireland). School of Physics, 2003)
    The aim of the research done for this thesis was to characterise the properties of a fibre laser producing ultrashort pulses at the telecommunication wavelength of 1550nm. We also measured the nonlinear optical properties ...
  • Preparation, characterisation and technological applications of half-metallic ferromagnetic oxides in ceramic and thin film form 

    Borges, Rui Pedro Nogueiro Gomes Morais (Trinity College (Dublin, Ireland). School of Physics, 2001)
    The aims of this study were: (i) to study the structural, magnetic and transport properties of ferromagnetic oxides (La0.7 Sr0.3)MnO3 and A2FeMoO6 (A=Ca, Sr, Ba) in polycrystalline and thin film form, (ii) to optimise the ...
  • The weakly coupled chiral Schwinger model on a finite lattice 

    Pinto, Carlos (Trinity College (Dublin, Ireland). School of Physics, 2000)
    The primary aim of this work is the development of a perturbative analysis of the phase structure of the lattice Schwinger model. A novel method for implementing this analysis is presented. It is shown analytically that ...
