Multidiagnostic analysis of ultrafast laser ablation of metals with pulse pair
(2010)
Copper targets are irradiated in the ablation regime by pairs of equal, time-delayed collinear laser
pulses separated on a timescale going from 2 ps to 2 ns. The ablation plume is characterized by
ion probe diagnostic, ...
Surface studies of the Fe/Mo(110) and Fe/W(100) epitaxial systems
(Trinity College (Dublin, Ireland). School of Physics, 2001)
This thesis describes the investigation of ultrathin Fe film growth on the Mo(110) and W(100) surfaces, using scanning tunneling microscopy (STM), low-energy electron diffraction (LEED) and Auger electron spectroscopy ...
Polarization dependent gain in Pr3+/Yb3+ doped fluoride fibre
(2008)
Fibre amplifiers and lasers are formed by introducing rare-earth ions into silica and fluoride fibre material. The
advantage of fluoride glasses is the much more efficient upconversion lasing in co-doped systems such as ...
Experimental reconstructions of 3D atomic structures from electron microscopy images using a Bayesian genetic algorithm
(2022)
We introduce a Bayesian genetic algorithm for reconstructing atomic models of monotype crystalline nanoparticles from a single projection using Z-contrast imaging. The number of atoms in a projected atomic column obtained ...
Nonlinear absorption properties of some 1,4,8,11,15,18,22,25-octaalkylphthalocyanines and their metallated derivatives
(2003)
The third-order nonlinear optical properties of a series of 15 unmetallated and metallated 1,4,8,11,15,18,22,25-octaalkylphthalocyanines have been investigated. The palladium-metallated compound is the strongest nonlinear ...
CrO2 : a general study
(Trinity College (Dublin, Ireland). School of Physics, 2000)
The aims of this work were (i) to prepare chromium dioxide, CrO2, in thin film and
powder form (ii) to study its magnetic, electronic and thermal properties and (iii) to
introduce thin films of CrO2 into a multilayer device ...
Single pulse all-optical toggle switching of magnetization without gadolinium in the ferrimagnet Mn2RuxGa
(2020)
Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been demonstrated, but so far only in Gd-based ...
Anomalous length dependence of the conductance of graphene nanoribbons with zigzag edges
(2013)
Charge transport through two sets of symmetric graphene nanoribbons with zigzag shaped edges in a two-terminal device has been investigated, using density functional theory combined with the non-equilibrium Green's function ...
A double-tuned 1H/23Na dual resonator system for tissue sodium concentration measurements in the rat brain via Na-MRI
(2010)
A method for quantifying the Tissue Sodium Concentration (TSC) in the rat brain from 23Na-MR images was developed. TSC is known to change in a variety of common human diseases and holds considerable potential to contribute ...
Investigating the Feasibility of Photostimulation for the Development of a Low Energy-Spread Electron Microscope Source.
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
Electron microscopes use fast-moving electrons as illumination to generate high resolution images down to the atomic scale. They are a valuable tool in various research fields, from palaeontology to material science. Low ...
