The winds of low-mass stars and solar-wind evolution
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)Stellar winds affect the evolution of stars (as well as impacting the planets orbiting these stars) through the removal of angular momentum and mass over time. This process changes the rotation rate of the host star, which ... -
Working Principle of Tunable PlasmonicReflect-Array Metasurfaces
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)This thesis will explore the way in which plasmonic metasurfaces, hosting nano-scale metallic resonator elements, can be used as beam-steering devices. We will propose our own devices that will demonstrate anomalous ... -
X-ray and radio diagnostics of accelerated electrons in solar active regions
(Trinity College (Dublin, Ireland). School of Physics, 2015) -
X-ray Photoelectron Spectroscopy of Novel Ternary Materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)In this thesis the best synthesis conditions and compositional dependency of optoelectronic properties for novel ternary n-type amorphous Zinc Tin oxide (a-ZTO) and p-type nanocrystalline CuxCrO2 Transparent Conducting ... -
X-ray spectroscopic studies of the electronic structure of chromium based p-type transparent conducting oxides
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)In this thesis the electronic, optical, electrical, and mechanical properties of two p-type transparent conducting oxides will be explored, primarily by spectroscopic techniques. The initial chapters outline how the ... -
Young brown dwarfs and their environments : testing star and planet formation
(Trinity College (Dublin, Ireland). School of Physics, 2014)This thesis presents a new contribution to our understanding of the formation of brown dwarfs. From a description of their discovery, to an analysis of their disks and photospheres, it sheds new light on the conditions ...
