The Ecological Effects of Light Pollution: A Three Site (Bull Island, Trinity College Dublin & Killiney Hill) Comparative Study
(Trinity College Dublin, 2016)
This work reports on the study of three sites within Dublin to assess the potential implications of light pollution using in situ light measurements in conjunction with species sensitivity studies.
Origin of the Two-Dimensional Electron Gas at LaAlO3=SrTiO3 Interfaces: The Role of Oxygen Vacancies and Electronic Reconstruction
(2013)
The relative importance of atomic defects and electron transfer in explaining conductivity at the crystalline LaAlO3=SrTiO3 interface has been a topic of debate. Metallic interfaces with similar electronic properties ...

Controlling the Properties of a-ZTO and a-IGZO via Low Temperature Annealing and Novel Layered Structures
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
This thesis deals with the broader implications of amorphous ZnSnO
(a-ZTO) growth via two synthesis methods, examining the in-situ
resistivity monitoring approach to optimising a low-annealing temperature
<300 ?C and ...
Constructive and destructive interference of Kerker-type scattering in an ultrathin silicon Huygens metasurface
(2020)
High refractive index dielectric nanoparticles have provided a new platform for exotic light manipulation through the interference of multipole modes. The Kerker effect is one example of a Huygens source design. Rather ...
Transport Properties of Disordered Nanowire Networks: from Conducting Thin Films to Neuromorphic Applications
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
Nanowire networks have had much attention from the scientific community in the past two decades due to their potential in numerous technological applications. Central to these are the superior electrical properties manifested ...
Interferometer based in-band OSNR monitoring of single and dual polarisation QPSK signals
(IEEE Computer Society, 2010)
The in-band OSNR of SP and DP QPSK signals were measured over a range of 10 to 21dB ?1dB using a pair of polarisation independent Michelson fibre interferometers without the requirement for prior knowledge of the signal's ...
Interlayer dielectric function of a type-II van der Waals semiconductor: The HfS2/PtS2 heterobilayer
(American Physical Society (APS), 2019)
Heterogeneous stacks of two-dimensional transition-metal dichalcogenides can be arranged so as to have a type-II band alignment, where the valence band maximum and the conduction band minimum are located on different layers. ...
RKKY interaction between extended magnetic defect lines in graphene
(2014)
Of fundamental interest in the field of spintronics is the mechanism of indirect exchange coupling between
magnetic impurities embedded in metallic hosts. A range of physical features, such as magnetotransport and
overall ...
Dynamics of the plumes produced by ultrafast laser ablation of metals
(2010)
We have analyzed ultrafast laser ablation of a metallic target (Nickel) in high vacuum addressing both expansion dynamics of the various plume components (ionic and nanoparticle) and basic properties of the ultrafast laser ...
