Atomic Diffusion and Pulsation in Post-Common-Envelope Binary Stars
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)I study the evolution of peculiar low-mass, evolved stars. Two groups of interest are the core-helium-burning hot subdwarfs and the shell-hydrogen-burning low-mass pre-white dwarfs. Stars in both groups have had previous ... -
Structures of columnar packings with soft and hard spheres
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)Columnar structures refer to dense cylindrical packings of spheres. They are ubiquitous throughout botany, foams, and have recently also become popular in nanoscience. We investigate such structures by carrying out computer ... -
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. ... -
Exfoliation and sensing application of 2D - materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)In the past decade, graphene and layered material such as Transition metal dichalcogenides (TMDs) and Transition metal oxides (TMOs) have been investigated for their importance in several applications. For example, these ... -
The Optics and Photonics of Two-Dimensional Nanomaterials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)In this work, by using a broadspectrum angle-resolved absorption technique, we studied enhanced absorption from multi-layered materials with near-zero dielectric permittivity in the near-infrared. These materials, known ...
