Development of new 1D metal based nanomaterials: Synthesis, charaterisation and applications
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)The main aim of this project was to develop new 1D metal based nanomaterials and explore their use for potential applications in catalysis. This work involves the synthesis, characterisation, and application of new AuAg ... -
Effect of Catalyst Diameter on Vapour-Liquid-Solid Growth of GaAs Nanowires
(2014)GaAs nanowires were grown on (111)B GaAs substrates using the vapour-liquid-solid mechanism. The Au/Pt nanodots used to catalyse wire growth were defined lithographically and had varying diameter and separation. An in-depth ... -
Fabrication and characterisation of photonic nanowires
(SPIE, 2008)In recent years the application of nano-porous templates, such as anodic alumina and PTFE, in the production of cylindrical nanostructures has been vast. In our work we used porous alumina membranes to produce luminescent ... -
Highly emissive nanowires grown from CdTe nanocrystals in a phosphate buffer solution
(2005)We present details on the CdTe nanowires formation, which were found to grow in a standard physiological phosphate-buffered solution, including in-situ observation of growth with a confocal microscope. The choice of ... -
Material characterisation of nanowires with intrinsic stress
(2017)When fabricating nanowires in a doubly-clamped beam configuration it is possible for a residual axial stress to be generated. Here, we show that material characterisation of metal and semiconductor nanowires subjected ... -
Numerical investigation of the stability of Ag-Cu nanorods and nanowires
(2008)Molecular dynamics simulations have been employed to investigate thermally-induced phase separation processes in nanometer-sized Ag50 Cu50 rods and wires. In the absence of concentration gradients, the mechanism underlying ... -
Planar nanowire arrays formed by atomic-terrace low-angle shadowing
(2008)A relatively simple method for preparation of planar nanowire arrays on vicinal substrates by molecular beam epitaxy is presented. The atomic step-and-terrace morphology of vicinal substrates is used to produce a shadowing ... -
The Resistance of Cu Nanowire-Nanowire Junctions & Electro-Optical Modeling of Cu Nanowire Networks
(2020)Flexible transparent conductors made from networks of metallic nanowires are a potential replacement for conventional, non-flexible, and transparent conducting materials such as indium tin oxide. Cu nanowires are particularly ... -
Silver Nanowire Networks as Flexible, Transparent, Conducting Films: Extremely High DC to Optical Conductivity Ratios
(2009)We have used aqueous dispersions of silver nanowires to prepare thin, flexible, transparent, conducting films. The nanowires are of length and diameter close to 6.5 ?m and 85 nm respectively. At low thickness, the films ... -
"A single nanoscale junction with programmable multilevel memory"
(2014)Nanoscale devices that are sensitive to measurement history enable memory applications, and memristors are currently under intense investigation for robustness and functionality. Here we de-scribe the fabrication and ... -
Spin transport properties of triarylamine-based nanowires
(2014)Triarylamine-derivatives can self-assemble upon light irradiation in one-dimensional nanowires with remarkable hole transport properties. We use a combination of density functional theory and Monte Carlo simulations to ...
