  • Novel magnetic materials for spin electronic applications 

    Fitzgerald, Ciara Bridget (Trinity College (Dublin, Ireland). School of Physics, 2005)
    Among various types of semiconductors, oxide semiconductors are the most promising host compounds to realise high Curie temperatures with transition metal doping. Room temperature ferromagnetism in dilute oxide semiconductors ...
  • Synchrotron radiation studies of organic/inorganic semiconductor interfaces 

    Cabailh, Grégory (Trinity College (Dublin, Ireland). School of Physics, 2005)
    Organic semiconductor molecules are often employed as a thin film interlayer to improve electronic and optoelectronic devices. The characterisation of the interface is thus important to understand the physical properties ...
  • Electrodeposition of coercive ferromagnetic films 

    Filho, Fernando Mário Rhen (Trinity College (Dublin, Ireland). School of Physics, 2005)
    The need for even more compact and low power consumption devices has been the driving force for microeiectromechanical systems (MEMS). Also the integration of MEMS into current state of the art silicon technology has set ...
  • Stability and motion of foams and films in confined geometries 

    Drenckhan, Wiebke (Trinity College (Dublin, Ireland). School of Physics, 2005)
    The last 20 years of research in the physics of foams display the development of a thorough understanding of dry and static foams. In the realm of wet and dynamic foams, however, many interesting and puzzling effects have ...
  • Rheological and local fluid dynamics in foams 

    Craus, Maria Dolores Alonso (Trinity College (Dublin, Ireland). School of Physics, 2005)
    This thesis explores the physics of foams, particularly those that are wet (i.e. have a high liquid fraction). The properties which are measured here relate to structure, drainage and rheology. We have performed the first ...
  • The influence of the laser induced plasma in the pulsed laser depositon of ZnO 

    de Posada, Eduardo (Trinity College (Dublin, Ireland). School of Physics, 2005)
    The thesis is divided in three main sections, two of them Chapter 2 and 3 are devoted to the study and analysis of the laser produced plasma. Finally in the third section (Chapter 4) the conclusions obtained in the first ...
  • STM study of the (001) and (110) surfaces of magnetite 

    Ceballos, Sergio F. (Trinity College (Dublin, Ireland). School of Physics, 2005)
    In this thesis the surface of single crystals and thin films of magnetite (001) and (110) have been studied by scanning tunneling microscopy (STM), scanning tunneling spectroscopy (STS), Auger electron spectroscopy (AES) and ...
  • Computational modelling of novel permanent magnetic designs 

    Hilton, James (Trinity College (Dublin, Ireland). School of Physics, 2005)
    Moderm permanent magnetic materials provide unique design opportunities as their low susceptibility makes them effectively transparent to external magnetic fields. This also simplifies the calculation of magnetic fields ...
  • The impact of protostellar jets on their environment 

    O'Connell, Barry F. (Trinity College (Dublin, Ireland). School of Physics, 2005)
    The nature of the accelerated and heated gas along collimated outflows emanating from deeply embedded protostars is investigated. By analysing the shock structures and excitation conditions it is possible to deduce information ...
