Charge trapping centers in TlInS1.9Se0.1 single crystals have,been studied by thermally stimulated current (TSC) technique. The measurements revealed that there are several trapping levels associated with the overlapping peaks in the spectrum. The experimental evidence indicates that all peaks in the TSC spectrum involve the slow retrapping processes. The trapping centers have been determined at the energies of 0.10 eV, 0.13 eV, 0.27 eV, 0.30 eV, 0.32 eV, 0.33 eV and 0.34 eV. The temperature-dependent frequency factors and capture cross sections together with the concentrations of the corresponding traps are evaluated. Present experimental results also indicate that the traps asssociated with the individual peak in the TSC spectrum are closely spaced and/or continuous.

Trapping parameters of repulsive centers in SbSI single crystals
Ozdemir, S; Firat, T; Mamedov, AM (Elsevier BV, 2004-06-08)
Charge trapping centers in antimony sulphide iodide (SbSI) single crystals have been investigated by the use of thermally stimulated current (TSC) technique. The TSC spectrum consists of only one apparent peak which is found to be associated with a single trapping level. Those traps are experimentally found to obey the monomolecular kinetics. The trapping parameters as the energy depth, temperature dependent frequency factor and capture cross section together with the concentrations of the corresponding dis...
Trap levels in layered semiconductor Ga2SeS
Aydinli, A; Hasanlı, Nızamı; Aytekin, S (Elsevier BV, 2004-12-01)
Trap levels in nominally undoped Ga2SeS layered crystals have been characterized by thermally stimulated current (TSC) measurements. During the measurements, current was allowed to flow along the c-axis of the crystals in the temperature range of 10-300 K. Two distinct TSC peaks were observed in the spectra, deconvolution of which yielded three peaks. The results are analyzed by curve fitting, peak shape and initial rise methods. They all seem to be in good agreement with each other. The activation energies...
Trapping levels in TlGaSe2 single crystals
Ozdemir, Selahattin; ALTINDAL, ŞEMSETTİN (Elsevier BV, 2013-07-25)
Charge trapping centers in TlGaSe2 single crystals were investigated by the use of thermally stimulated current (TSC) technique. The measurements of TSC spectra in the temperature range from 90 K to 300 K were performed at a constant heating rate. The measurements showed that there are several trapping levels associated with the complex structure of overlapping peaks in the spectrum. The TSC spectra are dominated by two levels appeared at 204.1 K and 220.1 K. The experimental results indicate that the traps...
Trap characterization by photo-transferred thermoluminescence in MgO nanoparticles
IŞIK, MEHMET; Hasanlı, Nızamı (Elsevier BV, 2018-05-15)
Shallow trapping centers in MgO nanoparticles were characterized using photo-transferred thermoluminescence (TL) measurements. Experiments were carried out in low temperature range of 10-280 K with constant heating rate. Shallow traps were filled with charge carriers firstly by irradiating the sample at room temperature using S-90/Y-90 source and then illuminating at 10 K using blue LED. TL glow curve exhibited one peak around 150 K. Curve fitting analyses showed that this peak is composed of two individual...
Trapping center parameters of TlGaSe2 layered crystals
Yuksek, NS; Kavas, H; Hasanlı, Nızamı; Ozkan, H (Elsevier BV, 2004-02-15)
Thermally stimulated current measurements are carried out on as-grown TlGaSe2 layered single crystals in the temperature range of 90-220 K with various heating rates. Experimental evidence is found for the presence of two trapping centers with activation energy 98 and 130 meV. The retrapping process is negligible for these levels, as confirmed by good agreement between the experimental results and theoretical predictions of the model that assumes slow retrapping. The calculation yielded 2.3 x 10(-24) and 1....
