Charge transport effects in field emission from carbon nanotube-polymer composites
(American Institute of Physics, 2006)
Electron field emission measurements have been made on multiwall arc discharge carbon nanotubes
embedded in a conjugated polymer host. Electron emission at low nanotube content is observed and
attributed to an enhancement ...
Theory of the exchange coupling in magnetic metallic multilayers
(American Physical Society, 1994)
Existing theories of the oscillatory exchange coupling in magnetic metallic multilayers are reconciled within a common approach. It is shown that Ruderman-Kittel-Kasuya-Yosida?type theories and full-confinement quantum-well ...
Multiwavelength Observations of Solar Magnetic Phenomena and Particle Acceleration
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
The solar magnetic field is instrumental in controlling the dynamics and topology of all coronal phenomena. The magnetic flux we observe varies by a factor of ~8 over a twenty-two year cycle causing a modulation in the ...
Tuning and characterization of self-assembled plasmonic nanoparticle arrays
(Trinity College (Dublin, Ireland). School of Physics, 2015)
This thesis details the development and use of a novel nano-entity fabrication technique. The technique is based on a glancing angle deposition (GLAD) on transparent stepped templates. It is demonstrated that the technique ...
Magnetic and transport properties of epitaxial stepped Fe3O4(100) thin films
(2014)
We investigate the magnetic and transport properties of epitaxial stepped Fe3O4 thin films grown with different thicknesses. Magnetization measurements suggest that the steps induce additional anisotropy, which has an easy ...
Effect of Chemical Precursors On the Optical and Electrical Properties of p‐Type Transparent Conducting Cr2O3:(Mg,N)
(2013)
Cr2O3:(Mg,N) has been reported as a p-type transparent conducting oxide. In this
contribution the effect of each precursor used for the deposition by spray-pyrolysis,
will be explored and their role in determining the ...
Photons in restricted topologies
(Trinity College (Dublin, Ireland). School of Physics, 2016)
In this work we discuss three different aspects of the topological classification of propagating beams of light. This topological classification relies on global properties of the light beam, which are insensitive to local ...
An experimental realisation of the Weaire-Phelan structure in monodisperse liquid foam
(2012)
The Weaire-Phelan (WP) structure is the lowest energy structure known of an ideal monodisperse foam in the dry limit. To date, it has not been realized in the laboratory. Instead Lord Kelvin's 1887 structure, which it ...
Measurement of electron temperature and state of ionization in laser-produced plasmas by use of dielectronic satellite lines
(American Physical Society, 1989)
