An exploration of two-dimensional materials for solar energy harvesting
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)
The rise in energy demand around the globe can only be met with sustainable and long-term reliance on alternative renewable energy sources. In this context, the goal of this thesis is to conceive a method through which ...
In-situ characterisation of one-dimensional plasmonic Ag nanocluster arrays
(2011)
One-dimensional Ag nanoparticle arrays have been grown on step-bunched vicinal Al2O3 in ultrahigh vacuum using deposition at a glancing angle. The structures grown showed a strong optical anisotropy in the visible region ...
Linear Jacobi-Legendre expansion of the charge density for machine learning-accelerated electronic structure calculations
(2023)
As the go-to method to solve the electronic structure problem, Kohn-Sham density functional
theory (KS-DFT) can be used to obtain the ground-state charge density, total energy, and several
other key materials’ properties. ...
An electron paramagnetic resonance study of carbon based electronic materials
(Trinity College (Dublin, Ireland). School of Physics, 2000)
Electron paramagnetic resonance (EPR) measurements have been made on films of hydrogenated amorphous carbon (a-C: H) and ion implanted 6H-SiC. We examine several sets of a-C: H films. The first and second sets of films ...
Transition voltages of vacuum-spaced and molecular junctions with Ag and Pt electrodes
(2014)
The transition voltage of vacuum-spaced and molecular junctions constructed with Ag and Pt electrodes is investigated by non-equilibrium Green's function formalism combined with density functional theory. Our calculations ...
Fractal Growth of a Conventional Calamitic Liquid Crystal
(2004)
We report observation of liquid crystal phase ordering via fractal growth aggregates for a calamitic, non-bent-core mesogen. Fractal growth of a conventional smectic-C (Sm-C) phase from the isotropic melt after a temperature ...
Mechanical properties of carbon nanotube polymer composites
(Trinity College (Dublin, Ireland). School of Physics, 2002)
In this study the production and optimisation of carbon nanotubes using the arc discharge method was investigated. The soot produced was analysed for the nanotube content. To remove the nanotubes from the soot a novel ...
Growth and electrical transport of germanium nanowires
(American Institute of Physics, 2001)
Single crystalline germanium nanowires have been synthesized from gold nanoparticles based on a vapor-liquid-solid growth mechanism. Germanium powder was evaporated at 950?C, and deposited onto gold nanoparticles at 500?C ...
Ab initio study of alkali-metal-based bismuth selenides (A BiSe2; A = K, Na) for photovoltaic and thermoelectric applications
(2024)
Iron pentacarbonyl (IPC) gas forms upon the reaction of carbon monoxide with Fe containing metallic surfaces under gas reforming conditions. IPC formation can sometimes reach alarming levels that cause metal loss, pipeline ...
Real-World Urban Light Emission Functions and Quantitative Comparison with Spacecraft Measurements
(2023)
We provide quantitative results from GIS-based modelling of urban emission functions for a range of representative low- and mid-rise locations, ranging from individual streets to residential communities within cities, as ...
