Thermal and Athermal Characterisation of Slotted Semiconductor Lasers
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
Over the past few decades, the world has experienced a revolution in information and communications technologies that has affected almost every aspect of modern life. The growth in internet capabilities and services has ...
Surface plasmon on topological insulator/dielectric interface enhanced ZnO ultraviolet photoluminescence
(2012)
It has recently been predicted that the surface plasmons are allowed to exist on the
interface between a topological insulator and vacuum. Surface plasmons can be
employed to enhance the optical emission from various ...
Quasiperiodic quantum heat engines with a mobility edge
(2020)
Steady-state thermoelectric machines convert heat into work by driving a thermally generated charge current against a voltage gradient. In this work, we propose a new class of steady-state heat engines operating in the ...
Electron correlation and magnetism in molecules and solids.
(Trinity College (Dublin, Ireland). School of Physics, 2011)
In order to understand the magnetic properties of solids and molecules, an accurate
description of the underlying microscopic many-electron systems is required. This can
be achieved through several theoretical and computational ...
Role of longitudinal fluctuations in L10 FePt
(American Physical Society (APS), 2019)
L10 FePt is a technologically important material for a range of novel data storage applications. In the ordered FePt structure the normally nonmagnetic Pt ion acquires a magnetic moment, which depends on the local field ...
Negative magnetoresistance in Fe3O4/Au/Fe spin valves
(American Physical Society, 2004)
The structural, electrical, and magnetic properties of Fe3O4 /Au/Fe spin valves on MgOs001d are presented.
In contrast to more conventional spin valve structures, the current-in-plane resistance of the Fe3O4 /Au/Fe ...
Origami-based spintronics in graphene
(2013)
We show that periodically folded graphene sheets with enhanced spin-orbit interaction due to curvature effects can carry spin-polarized currents and have gaps in the electronic spectrum in the presence of weak magnetic ...
Polymer reinforcement using liquid-exfoliated boron nitride nanosheets
(2013)
We have exfoliated hexagonal boron nitride by ultrasonication in solutions of polyvinylalcohol in water. The resultant nanosheets are sterically stabilised by adsorbed polymer chains. Centrifugation-based size-selection ...
Electrodeposition of coercive L10 FePd and FePt magnets
(Elsevier, 2010)
We report the preparation, characterization of structure and magnetic properties of electrodeposited L10 FePt films
with high coercivity. Equiatomic as-deposited films are nanocrystalline, soft and magnetically isotropic. ...
