In this work, the dark electrical resistivity, charge carrier density and Hall mobility of Tl(2)InGaSe(4) single crystal have been recorded and analyzed to investigate the dominant scattering mechanism in the crystal. The data analyses have shown that this crystal exhibits an extrinsic n-type conduction. The temperature-dependent dark electrical resistivity analysis reflected the existence of two energy levels as 0.396 and 0.512 eV, being dominant above and below 260 K, respectively. The temperature dependence of the carrier density was analyzed by using the single-donor-single-acceptor model. The latter analysis has shown that the above maintained 0.512 eV energy level is a donor impurity level. The compensation ratio for this crystal is determined as 0.96. The Hall mobility of Tl(2)InGaSe(4) is found to be limited by the scattering of electron-acoustic phonon interactions. The calculated theoretical acoustic phonon scattering mobility agrees with the experimental one under the condition that the acoustic deformation potential is 12.5 eV.

Reflectance spectra and refractive index of a Nd : YAG laser-oxidized Si surface Aygun, G; Atanassova, E; Turan, Raşit; Babeva, T (Elsevier BV, 2005-02-15) The reflectance spectra and refractive index of Nd:YAG laser-oxidized SiO2 layers with thicknesses from 15 to 75 nm have been investigated with respect to the laser beam energy density and substrate temperature. Thickness and refractive index of films have been determined from reflectance measurements at normal light incidence in the spectral range 300-800 nm. It was found that the oxide-growth conditions at higher substrate temperatures and laser powers greater than 3.36 J cm(-2) provides a better film qua...
Electron-phonon short-range interactions mobility and p- to n-type conversion in TlGaS2 crystals Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2006-02-01) The conductivity type conversion from p- to n-type at a critical temperature of 315 K in TlGaS2 crystals is observed through the Hall effect measurements in the temperature range of 200-350 K. 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 hole and electron effective masses of 0.36m(0...
Resonant Raman scattering near the free-to-bound transition in undoped p-GaSe Hasanlı, Nızamı; Ozkan, H (Wiley, 2001-01-01) Raman spectra of GaSe layered crystal have been measured using a He-Ne laser and temperature tuning the free-to-bound gap in the range 10-290 K. Resonance enhancement of E'((12)) mode has been observed for both incident and scattered photon energies equal to the free-to-bound transition energy.
Analysis of the Hall effect in TlGaTe2 single crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (IOP Publishing, 2009-06-10) The electrical resistivity and Hall coefficient of p-type TlGaTe2 crystals were measured in the temperature range of 110-320 K. The electrical resistivity, charge carrier density and Hall mobility data for the crystals have been analyzed by means of existing theories and models to determine the extrinsic energy levels, the carrier effective mass, the donor and acceptor concentrations and the dominant scattering mechanism in the crystal as well. The analysis of the temperature-dependent electrical resistivit...
Thermal lattice scattering mobility and carrier effective mass in intrinsic Tl2InGaTe4 single crystals Qasrawi, A. F.; Hasanlı, Nızamı (IOP Publishing, 2007-04-18) Systematic structural, dark electrical resistivity and Hall coefficient measurements have been carried out on n- type Tl2InGaTe4 single crystals. The data from x- ray powder diffraction allowed determination of the tetragonal unit cell lattice parameters. Analysis of the electrical resistivity and carrier concentration, which was recorded in the temperature range 210 - 350 K, reveals the intrinsic type of conduction with an average energy band gap of 0.85 eV. The temperature- dependent Hall mobility was obs...
