Langmuir probe characterization of laser ablation plasmas
(Elsevier, 2009)
For laser ablation plumes that are significantly ionized, Langmuir probes have proved to be a useful tool for measuring the plume shape, ion energy distribution, and electron temperature. Typically in laser ablation plasmas ...
Utilising Chromium-Based p-Type Transparent Conducting Oxides in Photovoltaic Devices
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
This thesis deals with the growth of modern, highly performing p-type transparent conducting oxides and their utilisation in two types of photovoltaic devices. X-ray spectroscopic techniques are used to understand the ...
Spectral linewidth and tuning requirements of sources for gas sensing in space-based applications at 935nm
(2006)
The spectral linewidth and tuning requirements of an external cavity laser (ECL) in the Littrow architecture and a distributed feedback (DFB) device for space-based gas sensing were investigated. The wavelengths of both ...
Magnetic Field Enhancement of Water Evaporation in Confined Spaces
(2023)
Water is studied in confined environments where it evaporates into its own vapor. Simultaneous experiments are conducted for 0.4–0.5 µL droplets confined at the center of 54 mm long microchannels with a cross section of ...
Growth of ZnO:Al by atomic layer deposition: Deconvoluting the contribution of hydrogen interstitials and crystallographic texture on the conductivity
(2019)
Aluminium doped ZnO (AZO) is an interesting low cost transparent conducting oxide with further use as an inorganic transport layer in multilayer solar cells. Here we present our work on atomic layer deposited (ALD) thin ...
Magneto-optic Kerr effect in a spin-polarized zero-moment ferrimagnet
(2018)
The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetization of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically distinct sublattices, such as rare-earth ...
The structure of monodisperse foam
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Equal-sized bubbles of average diameter less than one millimetre are found to
spontaneously crystallise upon formation. While previously employed by Sir
Laurence Bragg as an ideal system with which to study crystalline ...

A novel scanning probe micoscopy study of the (110) surface of rutile titanium dioxide
(Trinity College (Dublin, Ireland). School of Physics, 2008)
This work describes the application of a novel multi-parameter scanning probe technique
to the study of a model semiconductor and a metal oxide surface. Our novel
scanning probe technique enables the simultaneous measurement ...
