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 discrete trapping level are determined. The TSC signal is found to be strongly dependent on illumination temperature of the sample and this is explained by the model in which the traps are considered to be surrounded by repulsive potential barriers.

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 levels in layered semiconductor TlInS1.9Se0.1 Ozdemir, S; Hasanlı, Nızamı; Bucurgat, M (Wiley, 2003-04-01) 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 frequ...
Thermally stimulated currents in n-InS single crystals Hasanlı, Nızamı; Yuksek, NS (Elsevier BV, 2003-03-24) Thermally stimulated current measurements are carried out on as-grown n-InS single crystals in the temperature range of 10-125 K. Experimental evidence is found for four trapping centers present in InS. They are located at 20, 35, 60 and 130 meV. The trap parameters have been determined by various methods of analysis, and they agree well with each other.
Transient and steady state photoelectronic analysis in TlInSe2 crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Elsevier BV, 2011-08-01) The temperature and illumination effects on the transient and steady state photoconductivities of TlInSe2 crystals have been studied. Namely, two recombination centres located at 234 and at 94 meV and one trap center located at 173 meV were determined from the temperature-dependent steady state and transient photoconductivities, respectively. The illumination dependence of photoconductivity indicated the domination of sublinear and supralinear recombination mechanisms above and below 160 K, respectively. Th...
Crystal data and indirect optical transitions in Tl2InGaSe4 crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Elsevier BV, 2008-06-03) The room temperature crystal data and the optical properties of the Bridgman method grown Tl2InGaSe4 crystals are reported and discussed. The X-ray diffraction technique has revealed that Tl2InGaSe4 is a single phase crystal of monoclinic structure. The unit cell lattice parameters, which were recalculated from the X-ray data, are found to be a = 0.77244 nm, b = 0.64945 nm, c = 0.92205 nm and beta = 95.03 degrees. The temperature dependence of the optical band gap of Tl2InGaSe4 single crystal in the tempera...
