The Raman spectra of TlInS2xSe2(1-x) layered mixed crystals were studied for a wide composition range (0.25 <= x <= 1) in the frequency region 10-360 cm(-1) at room temperature. The shift of Raman-active phonon frequencies versus mixed crystals composition x were established. The effect of crystal disorder on the line width broadening of three high-frequency Raman-active modes is reported.

Compositional dependence of Raman-active mode frequencies and line widths in TlInS2xSe2(1-x) mixed crystals Guler, I.; Hasanlı, Nızamı (2014-11-01) The Raman spectra of mixed crystals TlInS2xSe2(1-x) have been investigated in the composition range of 0.25 <= x <= 0.75 and in the high-frequency region of 250-350 cm(-1) at room temperature. It was observed that Raman-active mode frequencies decrease as the selenium atoms content increases in the mixed crystals. The effect of crystal disorder on the line broadening of three high-frequency modes is reported.
Compositional Dependence of Optical Modes Frequencies in T1Ga(x)In(1-x)S(2) Layered Mixed Crystals (0 <= x <= 1) Isik, M.; Hasanlı, Nızamı; Korkmaz, F. (2014-09-01) The infrared transmittance and Raman scattering spectra in TlGaxIn1-xS2 (0 <= x <= 1) layered mixed crystals grown by the Bridgman method were studied in the frequency ranges of 400-2000 and 250-400 cm(-1), respectively. The bands observed at room temperature in IR transmittance spectra of TlGaxIn1-xS2 were interpreted in terms of multiphonon absorption processes. The dependences of the frequencies of IR- and Raman-active modes on the composition of TlGaxIn1-xS2 mixed crystals were also established. The str...
Temperature-dependent absorption edge and photoconductivity of Tl2In2S3Se layered single crystals Güler, Işıkhan; Ligonzo, T.; Hasanlı, Nızamı (2013-02-15) Temperature variation of indirect band gap of Tl2In2S3Se layered single crystals were obtained by means of absorption and photoconductivity measurements. The temperature coefficient of -7.1 x 10(-4) eV/K from absorption measurements in the temperature range of 10-300 K in the wavelength range of 520-1100 nm and -5.0 x 10(-4) eV/K from PC measurements in the temperature range of 132-291 K in the wavelength range of 443-620 nm upon supplying voltage V = 80 V were obtained. From the analysis of dark conductivi...
Raman frequency shifts calculated from the volume data in naphthalene Ozdemir, H.; Yurtseven, Hasan Hamit (2015-06-15) The Raman frequencies for modes of symmetry Ag and Bg are calculated as functions of temperature (at atmospheric pressure) and pressure (at room temperature) using the observed volume data from the literature through the mode Gruneisen parameters in naphthalene. By determining the temperature and pressure dependence of the isobaric (gamma(P)) and isothermal (gamma(T)) mode Gruneisen parameters, respectively, the Raman frequencies of the modes which were calculated, are in good agreement with the observed fr...
Optical properties of TlGaxIn1-xS2 layered mixed crystals (0 <= x <= 1) I. Composition- and temperature-tuned energy band gap Hasanlı, Nızamı (2010-05-28) Optical properties of the TlGaxIn1-xS2 mixed crystals (0 <= x <= 1) have been studied by means of transmission and reflection measurements in the wavelength range of 400-1100 nm. The optical indirect band gap energies were determined through the analysis of the absorption data. It was found that the energy band gaps increase with increasing of gallium atoms content in the TlGaxIn1-xS2 mixed crystals. From the transmission measurements carried out in the temperature range of 10-300K, the rates of change of t...
