Linear and nonlinear optical characterisation of self assembled nanostructures
(Trinity College (Dublin, Ireland). School of Physics, 2012) -
Linear and nonlinear optical characterisation of silicon nanowire structures
(Trinity College (Dublin, Ireland). School of Physics, 2008)The morphological and optical properties of various silicon nanowire structures were investigated. Photoluminescence was produced by all of the nanostructures and was attributed to a variety of different mechanisms. Optical ... -
Linear and nonlinear optical properties of low-dimensional structures on vicinal silicon (111) surfaces
(Trinity College (Dublin, Ireland). School of Physics, 2008) -
Liquid phase exfoliation and dispersion of two dimensional materials
(Trinity College (Dublin, Ireland). School of Physics, 2014)Over the last few years, it has become clear that due to their high surface area and novel properties, two dimensional materials will be extremely useful both for fundamental studies and for a range of applications. Previous ... -
Liquid Phase Exfoliation of 2D Materials under Ambient Conditions
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)A technique developed by the Coleman group in 2008 called liquid phase exfoliation (LPE) has been shown to be effective for the delamination of any material exhibiting a layered structure. Molybdenum dioxide ... -
Liquid phase exfoliation of two dimensional crystals
(Trinity College (Dublin, Ireland). School of Physics, 2013) -
Local investigations of switchable rotaxane molecules at interfaces using atomic force microscopy
(Trinity College (Dublin, Ireland). School of Physics, 2008)Rotaxane molecules (interlocked molecules consisting of two parts bonded mechanically) have an inherent multi-stability. The relative positions of the submolecular components can be altered through external stimuli, a ... -
Localised surface plasmon mediated energy transfer in quantum dot systems
(Trinity College (Dublin, Ireland). School of Physics, 2015)Nonradiative energy transfer to metal nanoparticles (NPs) is a technique used for optical- based distance measurements which is often implemented in sensing. Both Forster resonant energy transfer (FRET) and nanometal surface ... -
Localized basis approach to many-body effects and dielectric response
(Trinity College (Dublin, Ireland). School of Physics, 2001)This thesis is a study of the optical and dielectric properties of semiconductors and insulators, and of the way in which these properties provide insight into the microscopic response of the interacting system. The central ... -
LOFAR tied-array imaging and spectroscopy of solar radio bursts
(Trinity College (Dublin, Ireland). School of Physics, 2016)The Sun is the source of the most powerful explosions in the solar system such as solar ares and coronal mass ejections (CMEs). These explosions can occur up to several times per day and they release up to 1032 ergs (1025 ... -
Low Frequency Observations of the Solar Corona using LOFAR
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)The Sun is a highly dynamic, active star, dictated by the evolution of its magnetic fields, which transition from periods of maximum activity to periods of minimum activity over an 11-year cycle. During solar maximum the ... -
Magnetic and Electronic Phenomena in Oxide Interfaces, Thin Films and Heterostructures
The miniaturisation and reduction of power consumption in modern integrated circuitry and active compo- nents such as sensors and memory demands the development of novel materials. These materials must not only have ... -
Magnetic and transport properties of magnetite based nanostructures
(Trinity College (Dublin, Ireland). School of Physics, 2009)In this thesis, we investigate the magnetic and transport properties of magnetite based nanostructures. We in particular investigate the magnetization and surface Verwey transition of magnetite thin film, interlayer ... -
Magnetic barcodes in molecular medicine
(Trinity College (Dublin, Ireland). School of Physics, 2010)The need for faster and more sensitive diagnostic systems for the early detection of many life-threatening diseases is the driving force behind the work in this thesis. A lab-on-a-chip prototype device incorporating a ...
