The Uniform Box Product of Some Spaces With One Non-Isolated Point
<p>In her thesis, Jocelyn Bell studied the properties of the uncountable Fort space and showed that it was normal, countably paracompact, and collectionwise Hausdorff. This paper answers some of the questions posed in that thesis and shows the space to be collectionwise normal, but not paracompact. …

AN EXPLORATION OF DEFECT-BASED SINGLE PHOTON SOURCES: ZINC OXIDE AND HEXAGONAL BORON NITRIDE
Isolated point defects in wide bandgap semiconductors are single photon sources with applications in quantum optics, precision sensing, and quantum information processing technologies. Although the nitrogen-vacancy center in diamond has historically garnered the most attention, efforts to discover …

Electrical characterisation of defects in wide bandgap semiconductors.
… states present in the layers originated from point or extended defects. There was good agreement between data on deep electronic levels obtained from DLTS and TAS experiments. A number of hole traps have been detected; the majority of these levels show an unusual dependence of the DLTS signal …

Electrically active defects in novel Group IV semiconductors.
… show any signatures that could be attributed to isolated point defects. This could be due to the fact that it was necessary to take the samples to higher temperatures in order to fully ionize the boron in the sample. The boron acceptor is at 0.37 eV above the valence band and therefore only about …

Analysis and Optimization of the Two-Phase Series Capacitor Buck DC-DC Converter
… Voltage Regulator Modules (VRMs) as well as non-isolated Point-of-Load (PoL) converters. The current sharing concept is the main feature of this 2-pscB topology, where series capacitor voltage is used to achieve current sharing without the need for a phase current sensing circuit or complicated …

Engineering Rare-Earth Based Color Centers in Wide Bandgap Semiconductors for Quantum and Nanoscale Applications
<p>For many years, atomic point-defects have been readily used to tune the bulk properties of solid-state crystalline materials, for instance, through the inclusion of elemental impurities (doping) during growth, or post-processing treatments such as ion bombardment or high-energy irradiation. Such …

Pairs of geometric foliations of regular and singular surfaces
… BDEs, and associate an affine invariant to such points. We show that one may associate a complex parameter to folded singularities that determines the relative positions of various curves of interest. We show that the BDEs asymptotic, characteristic, and principal curves are related to other …
