Long-chain amine-templated synthesis of gallium sulfide and gallium selenide nanotubes
(2016)We describe the soft chemistry synthesis of amine-templated gallium chalcogenide nanotubes through the reaction of gallium(iii) acetylacetonate and the chalcogen (sulfur, selenium) using a mixture of long-chain amines ... -
Magnetization, Anomalous Hall Effect and Single Pulse Partial All-optical Switching in Amorphous Rare-earth Transition-metal Thin Films
(Trinity College Dublin. School of Physics. Discipline of Physics, 2023)Research on rare-earth (R) transition-metal (T) thin films has a long history. A revival of interest in this field was sparked by the discovery of single pulse all-optical switching (SP-AOS) in a-GdFeCo1 alloy thin films ... -
Material selection for Spin-Transfer-Torque Magnetic Random Access Memories: a High-Throughput approach
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)A Spin-Transfer-Torque Magnetic Random Access Memory (STT-MRAM) is a complex multilayered structure, whose sensitive element is formed by two ferromagnetic layers sandwiching an insulator, acting as a tunnel barrier. The ... -
Models of wet two dimensional foams
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)In this thesis I used models and computer simulations to investigate the properties of two dimensional polydisperse foams from the dry limit of zero liquid fraction to the wet limit of 0.16 liquid fraction. Initially I ... -
Multi-scale analysis of current-driven spin dynamics in magnetic tunnel junctions
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)Magnetic materials are of fundamental importance for the next generation of sensing and storage applications. The operating principle of such devices is based upon manipulating the orientation of the atomic magnetic moments. ... -
Nanofabrication and electronic transport properties of silicon nanowires
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)This project develops a robust and reliable process to pattern sub 20 nm features in negative tone Hydrogen Silsesquioxane (HSQ) resist using high-resolution Electron Beam Lithography (EBL) and a low damage reactive ion ... -
Precise modification of 2D materials by gas ion beams
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018) -
A self-contained ground-state approach for the correction of self-interaction error in approximate density-functional theory
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)Density functional theory (DFT), in its approximate Kohn-Sham formalism, is a highly-acclaimed computational tool that affords the practical and expeditious calculation of ground-state properties of molecules and solids, ... -
Third-order Nonlinear Optical Response and Ultrafast Carrier Dynanics of 2D Materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)Two dimensional (2D) materials have been in the spotlight of scientific researchers in the last decade due to their outstanding chemical, physical, electronic, mechanical and optical properties in comparison to their bulk. ...
