Contact-resistivity and transport properties in lateral germanium nanowire devices
(Trinity College (Dublin, Ireland). School of Physics, 2013)
Quasi-one-dimensional materials, such as germanium nanowires, are anticipated to provide enhanced functionality for high-tech electronic and spin- tronic device components. The primary aim of this thesis is to study the ...
Electrical control of spin dynamics in finite one-dimensional systems
(2011)
We investigate the possibility of the electrical control of spin transfer in monoatomic chains incorporating
spin impurities. Our theoretical framework is the mixed quantum-classical (Ehrenfest) description of the ...
High throughput secondary electron imaging of organic residues on a graphene surface.
(2014)
Surface organic residues inhibit the extraordinary electronic properties of graphene, hindering the development of graphene electronics. However, fundamental understanding of the residue morphology is still absent due to ...
Effect of a ferromagnetic STM cobalt tip on a single Co-phthalocyanine molecule adsorbed on a ferromagnetic substrate
(2021)
The effect of a ferromagnetic scanning tunneling microscope (STM) cobalt tip on the electronic, magnetic and electronic transport properties of a Co-phthalocyanine (CoPc)/Co(111) junction has been investigated in the ...
Pressure Dependent Mechanical Properties of Thin Films under Uniaxial Strain via the Layer Compression Test
(2023)
Amorphous materials can exhibit strong nonlinear mechanical properties in comparison to crystalline metals and ceramics, largely due to their non equilibrium state which depends on the means of sample preparation history. ...
Steps toward determination of the size and structure of the broad-line region in active galatic nuclei. 8: an intensive HST, IUE, and ground-based study of NGC 5548
(1995)
We present the data and initial results from a combined Hubble Space Telescope (HST)/IUE/ground-based spectroscopic monitoring campaign on the Seyfert 1 galaxy NGC 5548 that was undertaken in order to address questions ...
Nonlinear reflectivity of strongly coupled exciton-photon systems under resonant and non-resonant pumping
(2000)
Coupled exciton–photon systems are investigated using the pump–probe technique in order to gain a better understanding of the important mechanisms governing cavity–polariton nonlinear behaviour and dynamics. A semi-classical ...
Localized basis approach to many-body effects and dielectric response
(Trinity College (Dublin, Ireland). School of Physics, 2001)
This thesis is a study of the optical and dielectric properties of semiconductors and insulators, and of the way in which these properties provide insight into the microscopic response of the interacting system. The central ...
High-Mobility Flexible Transistors with Low-Temperature Solution-Processed Tungsten Dichalcogenides
(2023)
The investigation of high-mobility two-dimensional (2D) flakes beyond molybdenum disulfide (MoS2) will be necessary to create a library of high-mobility solution-processed networks that conform to substrates and remain ...
