Trapped Electron Centers and Trapped Hole Centers in Heavily Doped KCl: Tl. I. Thermal Glow Study

Journal of the Physical Society of Japan, 1979
Thermal glow curves of KCl crystals containing 0.2∼4.2 mole% of TlCl are measured after X-ray irradiation at 77 K. Trapped electron and trapped hole centers such as Tl 0 , Tl 2+ , Tl 2 + , (Tl 2 + )' and Tl 2 3+ centers are found to be concerned in the thermal glow phenomena.

Immuno‐Spin Trapping: Detection of Protein‐Centered Radicals

Current Protocols in Toxicology, 2005
AbstractProtein‐centered radicals are involved in biological oxidative damage induced by drugs, environmental hazards, and cellular reactive oxygen species. Presently, the technique most widely used to study protein‐centered radicals is electron spin resonance (ESR; also known as electron paramagnetic resonance, EPR); used either directly or in ...

Trapping Centers in Thermoluminescent Calcite

Physical Review, 1964
Trapping levels which account for most of the thermoluminescence in natural calcite have been investigated. Results are based on a study of color centers which are shown to be closely associated with the traps involved in thermoluminescence. Optical absorption measurements in a variety of Iceland-spar crystals show that the prominent calcite glow peaks

Coulombic and neutral trapping centers in silicon dioxide

Physical Review B, 1991
Ces pieges d'attraction coulombienne sont produits avec l'injection d'avalanche des trous a partir du substrat de silicium et de la capture ulterieure de certains de ces trous sur des sites lies a l'arsenic. Durant la photoemission interne des electrons a partir d'une porte fine d'Al, on determine les deplacements de tension dus a l'annihilation des ...

Deep muonium state in InSb: Recombination center vs. trapping center

Physica B: Condensed Matter, 2006
Abstract The bound state of an isotropic muonium atom has been detected in both n- and p-type InSb using a high-field μ SR technique. The hyperfine constant obtained for this center ( A = 2464 ± 1 MHz ) is characteristic of deep-level Mu 0 centers at tetrahedral interstitial sites in other cubic semiconductors, which ...

Isoelectronic Trap Like Luminescence Centers Of Ingan

MRS Proceedings, 1997
AbstractThis paper describes the characteristics of the luminescence centers observed in the various photoluminescence (PL) and photoluminescence excitation (PLE) spectra of hexagonal InxGa1−xN microcrystals, synthesized by the nitridation of sulfide in the In concentration range of 2%<x<6%.

Trapping of Hydrogen Molecules by M Centers

Journal of the Physical Society of Japan, 1973
Trapping of hydrogen molecules by M centers in KC1:U crystals has been investigated. The thermal bleaching of the M band converted optically from the F band was observed in the dark at 20, 30 and 40°C, and was explained by kinetic theory on diffusion of hydrogen molecules.

Trapping centers in heavy ion irradiated silicon

2014 International Semiconductor Conference (CAS), 2014
Low fluence heavy ions incident on high resistivity Si produce lattice defects which act as trapping centers, and produce also an important local field of strain. The strain field intensity increases with the increase of the difference in atomic size and mass between the ion and the Si atom host.

Electron trap centers in Ag-borate glasses

Journal of Non-Crystalline Solids, 1977
Abstract The center created by silver trapping an electron in borate glasses are considered. It is shown by ESR techniques that on trapping an electron, silver ions may form four types of centers: the single Ag0 or (Ag+ + e) centers, and, at higher Ag contents, the Ag0(Ag+) or (Ag+ + e) (Ag+) centers in which a second silver is involved.

Trapped-hole centers in alkaline-earth oxides

Journal of Physics and Chemistry of Solids, 1990
Abstract Alkaline-earth oxides frequently exhibit a visible coloration when stimulated with photons or ionizing radiation. The defects responsible for this coloration are often due to paramagnetic hole centers, which absorb over a broad spectrum in the visible and near-visible region.
