Constrained-DFT method for accurate energy-level alignment of metal/molecule interfaces
(2013)
We present a computational scheme for extracting the energy-level alignment of a metal/molecule interface,
based on constrained density functional theory and local exchange and correlation functionals. The method,
appl ...
Quantised conductance in a contact between metallic oxide crystals
(American Physical Society, 1998)
The conductance of a point contact between two crystals of metallic (La0.75Sr0.25)MnO3 shows steps as the contact is broken. A histogram of the conductance values observed in 60 breaks exhibits a series of sharp peaks at ...
Carbon Nanomaterials for Improved Performance of Perovskite Solar Cells Processed under High Humidity
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)
The work documented in this thesis concerns optimization of stacks of semiconducting materials for photovoltaic purposes. Hybrid organic-inorganic metal halide perovskite (MHP) is a promising semiconducting material for ...
Surface morphology of c-plane sapphire (á-alumina) produced by high temperature anneal
(2010)
A comparative study of the morphological surface evolution of c-plane (0001) alpha-Al2O3 upon annealing was investigated for non-miscut (i.e. substrates with 0 degrees nominal miscut) and vicinal substrates. The samples ...
Torque in nested Halbach cylinders
(IEEE, 1999)
Low Frequency Observations of the Solar Corona using LOFAR
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
The Sun is a highly dynamic, active star, dictated by the evolution of its magnetic fields, which transition from periods of maximum activity to periods of minimum activity over an 11-year cycle. During solar maximum the ...
Production of Quasi-2D Platelets of Non-Layered Iron Pyrite (FeS2) by Liquid-Phase Exfoliation for High Performance Battery Electrodes
(2020)
Over the last fifteen years, two-dimensional (2D) materials have been studied and exploited for many applications. In many cases, 2D materials are formed by the exfoliation of layered crystals such as transition-metal ...
Investigation of the physical mechanisms of shear-force imaging
(American Institute of Physics, 1996)
It is shown that shear-force imaging, as is commonly used for distance regulation in scanning near-field optical microscopy, is not a reliable technique for accurate topographic measurements. This is because different ...
Analyzing refractive index changes and differential bending in microcantilever arrays
(2008)
A new microcantilever array design is investigated comprising eight flexible microcantilevers introducing two solid bars, enabling to subtract contributions from differences in refractive index in an optical laser read out ...
Estimating stellar wind parameters from low-resolution magnetograms
(2017)
Stellar winds govern the angular momentum evolution of solar-like stars throughout their main-sequence lifetime. The efficiency of this process depends on the geometry of the star's magnetic field. There has been a rapid ...
