Among those ... -
Above the Clouds: Probing the atmospheres of ultra-hot Jupiters at high-resolution
(Trinity College Dublin. School of Physics. Discipline of Physics, School of Physics, 2025)One of the most surprising discoveries of the numerous exoplanet surveys conducted over the past two decades is the existence of close-in giant planets orbiting their host stars at orbital separations smaller than that of ... -
Two-Dimensional Materials for Tissue Engineering and Neural Interfacing Applications
(Trinity College Dublin. School of Physics. Discipline of Physics, Trinity College Dublin, School of Physics, 2025)The pages of a book behave very strangely compared to a block of wood - two-dimensional (2D) nanomaterials are no different. Offering unique properties that differ from their bulk counterparts, this simple change in ... -
Growth and characterisation of sustainable transparent conducting oxides
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)In this thesis the growth and optoelectronic properties of the ternary n-type amorphous zinc tin oxide (a-ZTO) and p-type crystalline V2O3 are discussed in the context of providing suitable and sustainable candidates for ... -
Searching for late-time interaction between Type Ia supernovae and distant circumstellar material using the Zwicky Transient Facility
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)The nature of the progenitor systems and explosion mechanisms that give rise to Type Ia supernovae (SNe Ia) is still debated. In rare cases the ejecta interact with circumstellar material (CSM) that was ejected from the ... -
Exact Conditions in Density Functional Theory and their application to Hubbard type Corrective Functionals
(Trinity College Dublin. School of Physics. Discipline of Physics, Trinity College Dublin, School of Physics, 2025)The work of this thesis falls within the topic of Kohn Sham (KS) and Generalised Kohn Sham (GKS) theory, the practical implementation of which are the most popular tools for predicting the electronic properties of atoms, ... -
Morphological & Electrical Characterisation of Nanosheet Networks
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Since the discovery of the stability and excellent electrical properties of the graphene monolayer, there has been a great deal of excitement about the superlative electrical, mechanical and thermal properties of 2D ... -
Thermodynamics of Nanoelectromechanics
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Taking inspiration from nanoelectromechanical experiments, we introduce a microscopic toy model consisting of a resonant-level quantum dot coupled to two electrodes and a single-mode oscillator. We derive a Fokker-Planck ... -
Piezoresistance and Electrical Conduction in Solution-Processed 2D Nanosheet Networks
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Nanosheet networks are attracting much interest as printed electronic devices, utilising the physical properties of 2D nanosheets. Electrical conduction and the impact of strain on conduction in the networks is of ... -
Investigation of Static & Active Structural Colouration in Ultrathin Film Lossy Fabry-Perot Resonator Stack Structures
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)The main aim of the research laid out in this work is to characterise the optical response of high index lossy absorbers like MoS2, Si, Ge, VO2, and Nio in various all-thin-film Fabry-Perot wave interference nanocavity ... -
An investigation of spectroscopic diversity in the pre-peak regime of thermonuclear supernovae
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)As the most commonly found transient in the night sky due to their high intrinsic brightness, Type Ia supernovae (SNe Ia) have shown themselves to be powerful cosmological tools due to their standardisable nature. There ... -
Bose condensation in nonequilibrium quantum gases: An adventure in the thermodynamics of light and matter
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Nonequilibrium condensates in microcavities have been extensively analysed over the past decades. Like equilibrium condensates, they are characterised by a macroscopic population of the ground state, however, the system ... -
Radio Imaging Spectroscopy of Eruptions in the Solar Corona
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Regularly, the Sun produces a variety of energetic explosive events, such as solar flares (sudden, intense bursts of electromagnetic radiation) and coronal mass ejections (CMEs) (large-scale expulsions of plasma and magnetic ... -
Tracking Solar Electron Beams from the Corona to the Heliosphere using Bayesian Methods
(Trinity College Dublin. School of Physics. Discipline of Physics, School of Physics, 2025)The Sun is an active star that produces the most powerful phenomena in the solar system, particularly flares and coronal mass ejections (CMEs). These violent explosions accelerate electrons and other solar energetic particles ... -
Following translation of individual proteins by single ribosomes in real-time using dual-trap optical tweezers
