The Trapping Centers of Electrons in Glass
1958In connection with his theory of the electric breakdown of amorphous substances, Frohlich suggested that in the glass state there should be various shallow electron traps below the conduction band, characteristic of the network structure of glass. On analizing our previous work on the electrical breakdown of glass, we arrived at the same inference ...

Molecular Trapped Centers in Atomic Cryocrystals
Journal of Low Temperature Physics, 2001Trapping of electronic excitations into molecular-like states in solid Xe, Kr, and Ar has been studied by cathodo- and photoluminescence spectroscopy. Radiative decay of these states exhibits features that may be related to the molecular trapped centers, which exist in the lattice of atomic cryocrystals prior to excitation of an electronic subsystem ...

Local Trapping Centers in the Ceramics of Eulytines
Journal of Applied Spectroscopy, 2003Thermally stimulated luminescence (TSL) of ceramics having the structure of eulytine Bi4X3O12 (X = Si, Ge, Zr) on exposure to x-ray irradiation in the temperature region 80–400 K is studied. An analysis of the forms of the TSL curves implies that the recombination processes in the TSL peaks at 149 and 212 K in Bi4Si3O12 ceramics and at 143 and 230 K in

Trapping center parameters in In6S7 crystals
Physica B: Condensed Matter, 2011Abstract Thermally stimulated current measurements were carried out on In 6 S 7 single crystals in the temperature range of 10–225 K with a constant heating rate of 0.8 K/s. The study of trapping centers was accomplished by the measurements of current flowing along the c -axis of crystals. The analysis of the glow curve according to various methods,

Trapping of Hydrogen Molecules by M Centers
Journal of the Physical Society of Japan, 1973Trapping 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.

Trapped-hole centers in irradiated Li3VO4
Journal of Applied Physics, 1993Defects in lithium vanadate (Li3VO4) exposed to x rays were studied by electron spin resonance (ESR). 77 K irradiation produces two types of trapped-hole centers. One is supposed to be carbonate radical CO3−, which is thermally stable even at room temperature.

The trapping centers of holes in a-As2Se3
Solid State Communications, 2004Abstract The density of the trapping centers and their capture radius for holes in a-As2Se3 are determined by analyzing the imaginary term of the modulated photocurrent. The light-induced changes in the imaginary term are also examined to study the influences of the photo structural changes to the density of states and to detect possible hole ...

Trapping centers in inse single crystals
Materials Chemistry and Physics, 1983Abstract A systematic investigation of centers acting in InSe single crystals has been carried out by means of the following electric and photoelectronic techniques: 1. a) Resistivity behaviour as a function of temperature, analyzed by the single donor-single acceptor model 2.

Charge Trapping Centers in Ferroelectric Ceramics
MRS Proceedings, 1992ABSTRACTElectron paramagnetic resonance (EPR), photo-thermal deflection spectroscopy (PDS), and electrical measurements have been used to characterize as-received and UV-lluminated lead lanthanum zirconate titanate (PLZT) and PZT ceramics. Following optical illumination we observe the activation of positively charged Pb+3 and negatively charged Ti+3 ...

Trapping Centers in Thermoluminescent Calcite
Physical Review, 1964Trapping 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
