Computer generation of structural models of amorphous Si and Ge
(1985)
We have developed and applied a computer algorithm that generates realistic random-network models of a-Si with periodic boundary conditions. These are the first models to have correlation functions that show no serious ...
Densest Columnar Structures of Hard Spheres from Sequential Deposition
(2011)
The rich variety of densest columnar structures of identical hard spheres inside a cylinder can surprisingly be constructed from a simple and computationally fast sequential deposition of cylinder-touching spheres, if the ...
Mesoscopic transport in ferromagnetic oxides
(Trinity College (Dublin, Ireland). School of Physics, 2002)
The study presented in this thesis is concerned with mesoscopic transport in half metallic ferromagnetic oxides. Two techniques have been developed to gain insight into the extrinsic transport properties of these oxides. ...
Temperature-dependent magnetic second-harmonic generation from Fe nanostructures grown on vicinal W(110)
(2011)
Temperature-dependent magnetic second-harmonic generation (MSHG) at normal incidence (NI) is used to determine magnetization curves from Au-capped ultrathin Fe nanostructures grown on a vicinal W(110) substrate. Aligned ...
The influence of QSO emission-line velocity shifts on estimates of the intergalactic background intensity
(1993)
Observations of the inverse effect indicate that the observed number of QSOs cannot provide sufficient radiation to reionize the intergalactic medium. We reanalyze the data set of one such study and show that bias in the ...
Quantifying the Trade-Off between Absolute Capacity and Rate Performance in Battery Electrodes
(2019)
Among other things, battery electrodes need to display large absolute capacities coupled with high rate performance. However, enhancing areal capacity, for example via increased electrode thickness, results in reductions ...
An observational overview of solar flares
(2011)
We present an overview of solar flares and associated phenomena,drawing upon a wide range of observational data primarily from the RHESSI era. Following an introductory discussion and overview of the status of observational ...
Defect annealing in a II-VI laser diode structure under intense optical excitation
(1998)
Defect annealing under intense pulsed optical excitation has been observed in a II?VI laser diode
structure at room temperature. More than one order of magnitude increase in photoluminescence
intensity has been obtained ...

Atomic and Electronic Structure of a Multidomain GeTe Crystal
(2020)
Renewed interest in the ferroelectric semiconductor germanium telluride was recently triggered by the direct observation of a giant Rashba effect and a 30-year-old dream about a functional spin field-effect transistor. In ...
