Tl3InSe4 single crystal has been successfully prepared by the Bridgman crystal growth technique. The crystal that is reported for the first time is found to be of tetragonal structure with lattice parameters of a=0.8035 and c=0.6883 nm. The electrical resistivity and Hall effect measurements on the crystal revealed a conductivity type conversion from p- to n-type at a critical temperature of 283 K. The electron to hole mobility ratio is found to be 1.10. The analysis of the temperature-dependent electrical resistivity, Hall coefficient and carrier concentration data reveals the extrinsic type of conduction with donor impurity levels that behave as acceptor levels when are empty. The data analysis allowed the calculation of the hole and the electron effective masses as 0.654m(0) and 0.119m(0), respectively. In addition, the temperature-dependent Hall mobility in the n-region is found to be limited by the electron-phonon short-range interactions scattering with an electron-phonon coupling constant of 0.21.

Design and characterization of TlInSe2 varactor devices QASRAWI, ATEF FAYEZ HASAN; Aljammal, Faten G.; Taleb, Nisreen M.; Hasanlı, Nızamı (Elsevier BV, 2011-07-15) TlInSe2 single crystal has been successfully prepared by the Bridgman crystal growth technique. The crystal, which exhibits compositional atomic percentages of 25.4%, 25.2% and 49.4% for TI, In and Se, respectively, is found to be of tetragonal structure with lattice parameters of a=0.8035 and c=0.6883 nm. The crystals were used to design radio frequency sensitive varactor device. The temperature dependence of the current-voltage characteristics of the device allowed the calculation of the room temperature ...
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...
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...
Observation of in situ enhanced crystallization, negative resistance effect and photosensitivity in Tl2InGaSe4 crystals Qasrawi, A. F.; Irshaid, Tahani M. A.; Hasanlı, Nızamı (Elsevier BV, 2021-02-01) In this work, we report the properties of Tl2InGaSe4 crystals as multifunctional material. Namely, Tl2InGaSe4 crystals are grown by the modified Bridgman method using mixtures of TlInSe2 (50%) and TlGaSe2 (50%) single crystals. The enhanced crystallization and structural stabilities are monitored by the X-ray diffraction technique during the in situ heating and cooling cycles. The structural analyses on the Tl2InGaSe4 crystals revealed domination of both of the monoclinic and tetragonal phases in the crysta...
Crystal data and some physical properties of Tl2InGaTe4 crystals Qasrawi, A. F.; Hasanlı, Nızamı (Wiley, 2007-08-01) The room temperature crystal data, Debye temperature, dark and photoelectrical properties of the Bridgman method grown Tl2InGaTe4 crystals are reported for the first time. The X-ray diffraction technique has revealed that Tl(2)lnGaTe(4) is a single phase crystal of tetragonal body-centered structure belonging to the D-4H(18) - I4mcm space group. A Debye temperature of 124 K is calculated from the results of the X-ray data. The current-voltage measurements have shown the existence of the switching property o...
