Multiple spin?phonon relaxation pathways in a Kramer single-ion magnet
(2020)
We present a first-principles investigation of spin-phonon relaxation in a molecular crystal of Co2+ single-ion magnets. Our study combines electronic structure calculations with machine-learning force fields and unravels ...
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 ...
Anisotropic magneto-transport properties of epitaxial magnetite thin films
(Trinity College (Dublin, Ireland). School of Physics, 2010)
In this thesis we investigate the anisotropic magneto-transport properties
of epitaxial Fe304 films grown on MgO substrates. In particular
we investigate the angular dependence of the anisotropic niagnetoresistance
(AMR), ...
Reflection-mode scanning near-field optical microscopy: Influence of sample type, tip shape, and polarization of light
(American Institute of Physics, 1998)
A reflection-mode aperture-type scanning near-field optical microscope (R-SNOM) based on the external collection of the reflected light is presented. The light detection is based on an elliptical mirror setup, with the tip ...
Spin filter effect of manganese phthalocyanine contacted with single-walled carbon nanotube electrodes.
(2010)
We present a theoretical study of the spin transport through a manganese phthalocyanine (MnPc) molecule sandwiched between two semi-infinite armchair single-walled carbon nanotube (SWCNT) electrodes. Ab initio modeling is ...
Coherence properties of the microcavity polariton condensate
(2009)
A theoretical model is presented which explains the dominant decoherence process
in a microcavity polariton condensate. The mechanism which is invoked is the effect of self-phase
modulation, whereby interactions transform ...
Structural and magnetic properties of planar nanowire arrays of Co grown on oxidized vicinal silicon (111) templates
(2012)
e fabricated planar arrays of Co nanowires (NWs) on oxidized step-bunched Si (111) templates using shallow angle deposition. These planar NW arrays exhibit ferromagnetic behavior at room temperature for NW widths down to ...
Far-UV Emissions of the Sun in Time: Probing Solar Magnetic Activity and Effects on Evolution of Paleo-Planetary Atmospheres
(American Astronomical Society, 2003)
We present and analyze Far Ultraviolet Spectroscopic Explorer (FUSE) observations of six solar analogs. These
are single, main-sequenceG0?5 stars selected as proxies for the Sun at several stages of its main-sequence ...
Magnetic second-harmonic generation from interfaces and nanostructures
(2010)
Magneto-optic techniques provide non-contact and non-destructive characterization of magnetic materials. This includes embedded magnetic nanostructures, which are accessible due to the large penetration depth of optical ...
