Using chronoamperometry to rapidly measure and quantitatively analyse rate-performance in battery electrodes
(2020)
For battery electrodes, measured capacity decays as charge/discharge current is increased. Such rate-performance is usually characterised via galvanostatic charge-discharge measurements, experiments which are very slow, ...
Nucleobase adsorbed at graphene devices: Enhance bio-sensorics
(2012)
Graphene as a good material for sensing single small molecules is hardly believed to identify bio-molecules via electrical currents. This is because bio-molecules tend to bind to graphene through non-covalent bonds, such ...
A TEM Heart Transplant: The Development of a User Adjustable Pole-piece (UAP)
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
Transmission Electron Microscopes (TEMs) have massively accelerated progress in many areas of science, particularly biology and material science. Atomic-scale resolution was achieved soon after the invention of the TEM, ...
Low magnetisation alloys for in-plane spin transfer torque devices
(2012)
Magnetic properties of thin films of three in-plane alloy systems, namely, Co40Ni40?xCrxB20, Co40Fe40?xNixB20, and Co40Fe40?xCrxB20 are investigated with a view to reducing the critical current density (jc ) for spin ...
Spectroscopic and Microscopic Characterisation of Liquid Phase Exfoliated 2D Materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)
Since the experimental isolation of graphene nearly two decades ago, the research into two-dimensional materials has accelerated at a tremendous rate across a vast range of scientific and engineering fields. Liquid phase ...
Conical diffraction and the dispersion surface of hyperbolic metamaterials
(2014)
Hyperbolic metamaterials are materials in which at least one principal dielectric constant is negative. We
describe the refractive index surface, and the resulting refraction effects, for a biaxial hyperbolic metamaterial,
with ...
Concept of a nanowire array magnetoresistance device
(2008)
We describe a concept of the magnetoresistive medium comprising of a planar array of intermingled nanowires with pinned and unpinned magnetic moments. We propose a bottom up method of forming the medium and demonstrate the ...
Thermodynamics of interacting many-body quantum systems
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)
Technological and scientific advances have given rise to an era in which coherent quantum-mechanical phenomena can be probed and experimentally-realised over unprecedented timescales in condensed matter physics. In turn, ...
Equilibrium faceting formation in vicinal Al2O3 (0001) surface caused by annealing
(Elsevier B.V., 2012-07)
We report on a heat-induced transformation of the surface of ?-alumina (0001) crystals which have an off-cut in the [1-210] direction. Annealing the crystal causes the surface to transform into a regular array of
(0001) ...
