Theory of defect complexes in insulators
Physical Review B, 2010Defect complexes exhibit intricate electronic spectra, which can neither be described as a superposition of the constituent defect spectra, nor via conventional perturbative treatment applied thereupon. Instead, one must evaluate changes in the all-electron wave function in order to predict defect complex spectra.

Effect of Defective RTV Coatings on Insulation Performance of Porcelain Insulators
2019 International Power System Conference (PSC), 2019In this work, the effects of defective RTV coatings on insulating performance of porcelain insulators and their performance improvement according to the electric field conditions are investigated. For this purpose, first, two samples of porcelain insulators with the defective coatings in the marginal points of the electric field (points where the ...

Effect of defects and moisture on insulation characteristics of XLPE insulated cable
Electrical Engineering in Japan, 1994AbstractSample cables having a few types of defects (such as voids, contaminants, and protrusions) with more volume than usual, were prepared intentionally to clarify how these defects affect separately insulation characteristics under the presence/nonpresence of moisture.

Defect characterization and control for SiGe-on-insulator
2010 10th IEEE International Conference on Solid-State and Integrated Circuit Technology, 2010Defects in SiGe-On-Insulator (SGOI) fabricated using Ge condensation by dry oxidation method were characterized by optical and electrical methods. The locations of main defect levels were determined to be above mid-gap for SGOI with low Ge fraction (Ge%), which tend to valance band direction and unintentionally induce high hole concentration in SGOI ...

EPR of defects in silicon-on-insulator structures
Radiation Effects, 1986Abstract Electron Paramagnetic Resonance measurements have been made on silicon-on-silicon dioxide and silicon-on-silicon nitride structures produced by ion implantation. In the former type of structure the EPR spectra have been ascribed to the oxygen vacancy centre E1” in the SiO2, the defect PMb0 at the Si/SiO2 interfaces and the amorphous silicon ...

Impurities and Defects in Topological Insulators
2012Impurities and defects in topological insulators can be regarded as system boundaries. Bound states may form around these impurities or defects for the same reason that the edge or surface states form.

Temporal Defects in Photonic Topological Insulators
Conference on Lasers and Electro-Optics, 2017We experimentally study time-dependent defects in a waveguide model of a topological insulator. Backscattering is not observed, but in contrast to static defects, edge modes propagate through the defects.

Defects in epitaxial insulating thin films
Journal of Physics: Condensed Matter, 1999Defects on thin epitaxial insulator films of NaCl(100), KCl(100), and MgO(100) generated during growth and by electron bombardment are investigated by high-resolution spot profile analysis in low-energy electron diffraction (SPALEED), photoelectron spectroscopy (XPS, UPS), electron energy-loss spectroscopy (EELS), and thermal desorption spectroscopy ...
