Tunable plasmonics with Au nanoparticles coupled to thin film vanadium dioxide
(2022)
The development of active devices featuring dynamic tunable plasmonic resonances is vital for wide implementation in many optoelectronic devices. By coupling plasmonic nanoparticles to an underlying thin film of phase ...
A comparison of He and Ne FIB imaging of cracks in microindented silicon nitride
(2018)
Helium ion microscopy (HIM) offers potential as a high spatial resolution technique for imaging insulating samples that are susceptible to charging artifacts. In this study helium and neon ion microscopy are used to image ...
Automatic detection and tracking of coronal mass ejections. II. Multiscale filtering of coronagraph images
(2012)
Studying CMEs in coronagraph data can be challenging due to their diffuse structure and transient nature, and user-specific biases may be introduced through visual inspection of the images. The large amount of data available ...
Optical and electrical properties of modified conjugated polymer thin films
(Trinity College (Dublin, Ireland). School of Physics, 2003)
The ability to control both the spectral and electrical stability of polymer light emitting devices are just two of the parameters that are paramount to their commercial viability. The presence of water vapour and oxygen ...
Quantum coherence and ergotropy
(2020)
Constraints on work extraction are fundamental to our operational understanding of the thermodynamics of both classical and quantum systems. In the quantum setting, finite-time control operations typically generate coherence ...
The wave properties of coronal bright fronts observed using SDO/AIA
(2011)
Coronal bright fronts (CBFs) are large scale wavefronts that propagate though the solar corona at hundreds of kilometers per second. While their kinemat- ics have been studied in detail, many questions remain regarding the ...
Nucleation field and energy product of aligned two-phase magnets - progress towards the '1 MJ/m3' magnet
(IEEE, 1993)
Exchange hardening of nanostructured two-phase systems composed of an aligned hard phase and a soft phase with high magnetization is investigated using a micromagnetic approach which accounts for intereactions between the ...
Modelling and Monitoring Geomagnetically Induced Currents in Ireland
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
This thesis is the first detailed study of the effects of geomagnetic storms and geomagnetically induced currents (GICs) on the Irish power network.
In order to better monitor geomagnetic storms in Ireland, a network of ...

Self-limited growth of triangular PtO2 nanoclusters on the Pt(111) surface
(2010)
The high temperature oxidation of the Pt(111) surface by molecular oxygen has been studied using scanning tunnelling microscopy (STM) and low-energy electron diffraction (LEED). Results indicate a self-limited growth of ...
