Trap centers in molybdates

Optical Materials, 2013
Charge carrier trapping centers have been studied in molybdates CaMoO4, SrMoO4 and PbMoO4 with the scheelite crystal structure as well as in ZnMoO4, which crystallize in a-ZnMoO4 structural type. The trap parameters such as activation energies and frequency factors have been determined.

Trap centers in cuprous oxide

Solid-State Electronics, 1988
Abstract The effect of annealing temperature on the trap density in Cu 2 O is investigated. From space charge limited current (SCLC), Hall effect and DLTS measurements it is demonstrated that there is a trap-band distribution with the Fermi level lying within the trap-band. The maximum of this trap-band distribution is just above the Fermi level.

Trapped Electron Centers and Trapped Hole Centers in Heavily Doped KCl: Tl. II. ESR Study

Journal of the Physical Society of Japan, 1979
In X-ray irradiated KCl crystals containing more than 1 mole% of TlCl, ESR signals of Tl 2 3+ centers which are characterized by g =2.04 have been newly observed. This pair center has a 6 s hole whose wavefunction is almost localized on one of the thallium ions (hyperfine constant A =105 GHz), and only a little fraction (about 1%) of the wavefunction ...

Copper in Germanium: Recombination Center and Trapping Center

Physical Review, 1956
The time-dependent photoconductivity of copper-doped $n$-type and $p$-type germanium bridges has been measured between 130\ifmmode^\circ\else\textdegree\fi{}K and 293\ifmmode^\circ\else\textdegree\fi{}K. Temporary hole traps were found in the $n$-type samples at the lower temperatures but no traps were observed in the $p$ type.

Traps and recombination centers in YALO3:Ce,Co

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002
Abstract It has recently been noted that notorious underperfomance of YAlO 3 :Ce scintillator (25–30 ns scintillation decay time at room temperature instead of 17 ns) is caused by uncontrolled traps that accompany Ce radiative recombination centers. A possible way to improve the material is to introduce a second intentional dopant that would assume a

Molecular Trapped Centers in Atomic Cryocrystals

Journal of Low Temperature Physics, 2001
Trapping 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 ...
