A computationally efficient method for calculating the maximum conductance of disordered nanowire networks
(2010)
Random networks of carbon nanotubes and metallic nanowires have shown to be very useful in the production of transparent, conducting films. The electronic transport on the film depends considerably on the network properties, ...
A dynamic study of cavity polaritons
(Trinity College (Dublin, Ireland). School of Physics, 2002)
Strong coupling between an atom and a cavity field is a well established phenomenon in the field of cavity quantum electrodynamics. However it was not until 1992 that improvements in growth technology resulted in the advent ...
Magnetic Resonance Imaging in Ophthamology
(2012)
Imaging the eye with magnetic resonance imaging (MRI) has proved difficult due to the eye?s propensity to move involuntarily
over typical imaging timescales, obscuring the fine structure in the eye due to the resulting ...
Electrochemical Applications of Two-Dimensional Nanosheets: The Effect of Nanosheet Length and Thickness
(2016)
Although many electrochemical properties of 2D materials depend sensitively on the nanosheet dimensions, there are no systematic, quantitative studies which analyse the effect of nanosheet size and thickness on electrochemical ...
The Jacobi-Legendre framework for Machine Learning in Materials Investigation and Discovery
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
Machine-learning models have rapidly become fundamental tools in the study of materials properties. In the past few years there has been a surge of interest in the construction of new models and descriptors to accelerate ...
High strength composite fibres from polyester filled with nanotubes and graphene
(2012)
We have prepared composite fibres based on the polyester, polyethylene terephthalate (PET), filled with both single walled nanotubes and graphene by a combination of solution and melt processing. On addition of ?2 wt% ...
Quantum Control of Thermodynamic Processes in Semiconductors
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
In this thesis, we explore theoretically the thermodynamics of heat exchange in laser driven solid state systems. In particular, we focus on the heat exchanged between phonons and a semiconductor quantum dot exciton, driven ...
Novel observations in internal conical diffraction
(Trinity College (Dublin, Ireland). School of Physics, 2015)
Internal conical diffraction occurs when a beam of light is incident along an optic axis direction in a biaxial material. The beam transforms into a hollow skewed cone inside the material and refracts upon exiting. The ...
Characterization of a multi-electrode bulk-SOA for low NF in-line amplification in passive optical networks
(2010)
A bulk semiconductor optical amplifier (SOA) utilizing a multi-contact biasing method is characterized as a function of the bias current supplied to each section Firstly, amplified spontaneous emission spectra and ...
