Mechanical and morphological properties of carbon nanotubes polymeric composites
(Trinity College (Dublin, Ireland). School of Physics, 2009)
Carbon nanotubes (CNT) are incorporated to the polymers to enhance their electrical and mechanical properties. All of the samples in this thesis were prepared from the liquid phase using the solution casting method. The ...
The electrical conductivity of solution-processed nanosheet networks
(2021)
Solution-processed networks of 2D nanosheets are promising for a range of applications in the field of printed electronics. However, the electrical performance of these networks represented for example by the mobility – ...
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, ...
Micromechanical sensing for real time monitoring of filamentous fungi growth
(Trinity College (Dublin, Ireland). School of Physics, 2013)
Since the early 1990s the use of cantilevers as biosensors has risen dramatically. Advances in semiconductor fabrication technologies has resulted in the reproducible production of high quality cantilever arrays. When ...
Planar Hall effect in magnetite (100) films
(American Institute of Physics, 2006)
Giant planar Hall effect (GPHE) has been observed in epitaxial magnetite (100) films grown on MgO substrates. The effect is manifested as jumps in the transverse resistivity when the film is subjected to a swept, in-plane ...
Oxygen Electromigration and Energy Band Reconstruction Induced by Electrolyte Field Effect at Oxide Interfaces
(2018)
Electrolyte gating is a powerful means for tuning the carrier density and exploring the resultant modulation of novel properties on solid surfaces. However, the mechanism, especially its effect on the oxygen migration and ...
Fast ab initio methods for the calculation of adiabatic spin wave spectra in complex systems
(American Physical Society, 2001)
The interpretation of the physics of magnets with reduced dimensionality often requires information on the
spin wave excitations at arbitrary wavelengths which is generally hard to obtain experimentally. Two powerful
methods ...
Numerical and experimental investigation of a novel waveguide design for use in high power laser diode devices
(Trinity College (Dublin, Ireland). School of Physics, 2002)
Because of their efficiency, small size and reliability high power laser diodes are used for
numerous tasks, such as the pumping of solid state lasers, second harmonic generation and the pumping of
rare earth fibre ...
Magnetic activity and hot Jupiters of young Suns: the weak-line T Tauri stars V819 Tau and V830 Tau
(2015)
We report results of a spectropolarimetric and photometric monitoring of the weak-line T Tauri stars (wTTSs) V819 Tau and V830 Tau within the MaTYSSE programme, involving the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii ...
Influence of annealing on the bias voltage dependence of tunnelling magnetoresistance in MgO double-barrier magnetic tunnel junctions with CoFeB electrodes
(American Institute of Physics, 2006)
Double-barrier magnetic tunnel junctions with two MgO barriers and three CoFeB layers exhibiting tunneling magnetoresistance (TMR) values of more than 100% were fabricated. The bias voltage dependence of the TMR ratio is ...
