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 structural characterization of the mixed crystals was investigated by means of X-ray diffraction measurements and compositional dependence of lattice parameters was revealed.

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.
Raman scattering in TlInS2xSe2(1-x) layered mixed crystals (0.25 <= x <= 1): Compositional dependence of the mode frequencies and line widths Güler, Işıkhan; Hasanlı, Nızamı (2011-09-15) 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.
Infrared and Raman scattering spectra of layered structured Ga3InSe4 crystals IŞIK, MEHMET; Hasanlı, Nızamı; KORKMAZ ÖZKAN, FİLİZ (2013-03-01) The infrared reflectivity and transmittance and Raman scattering in Ga3InSe4 layered crystals were investigated in the frequency ranges of 100-400, 400-4000 and 25-500 cm(-1). The refractive and absorption indices, the frequencies of transverse and longitudinal optical modes, high- and low-frequency dielectric constants were obtained from the analysis of the IR reflectivity spectra. The bands observed in IR transmittance spectra were interpreted in terms of two-phonon absorption processes.
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...
Compositional dependence of refractive index and oscillator parameters in T1GaS(2x)Se(2(1-x)) layered mixed crystals (0 <= x <= 1) Hasanlı, Nızamı (2012-09-14) Optical characterization of TIGaS2xSe2(1-x) mixed crystals have been carried out at room temperature using the transmission and reflection measurements in the wavelength range of 400-1100 nm. The spectral dependence of the refractive index for all compositions of studied crystals were obtained. The dispersion of the refractive index is discussed in terms of the Wemple-DiDomenico single-effective-oscillator model. The compositional dependencies of refractive index dispersion parameters: oscillator energy, di...
