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, dispersion energy and zero-frequency refractive index were revealed.

Refractive index and oscillator parameters in TlGaS2, TlGaSe2 and TlInS2 layered crystals Hasanlı, Nızamı (2011-01-01) The optical properties of TlGaS2, TlGaSe2, and TlInS2 crystals have been investigated through the transmission and reflection measurements at room temperature in the wavelength range of 400-1100 nm. These measurements allowed determination of spectral dependence of the refractive index for all crystals studied. The dispersion of the refractive index is discussed in terms of the Wemple-DiDomenico single-effective-oscillator model. The refractive index dispersion parameters: the oscillator energies, the dispe...
Temperature-dependent optical properties of GaSe layered single crystals Hasanlı, Nızamı (2016-8-01) Optical properties of GaSe single crystals have been investigated using temperature-dependent transmission and room temperature reflection measurements in the wavelength range of 380–1100 nm. The analysis of the absorption data at room temperature showed the existence of indirect transitions in the crystal with energy band gap of 1.98 eV. Temperature dependence of the transmission measurements revealed the shift of the absorption edge toward lower energy as temperature is increased from 10 to 280 K. The rat...
Temperature-dependent optical properties of GaSe layered single crystals IŞIK, MEHMET; TUĞAY, EVRİN; Gasanly, N. M. (2016-01-01) Optical properties of GaSe single crystals have been investigated using temperature-dependent transmission and room temperature reflection measurements in the wavelength range of 380-1100nm. The analysis of the absorption data at room temperature showed the existence of indirect transitions in the crystal with energy band gap of 1.98eV. Temperature dependence of the transmission measurements revealed the shift of the absorption edge toward lower energy as temperature is increased from 10 to 280K. The rate o...
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...
Optical properties of Tl2In2Se3S layered single crystals Güler, Işıkhan; Hasanlı, Nızamı (2010-01-01) The optical properties of Tl2In2Se3S layered single crystals have been analyzed using transmission and reflection measurements in the wavelength region between 500 and 1100 nm. The optical indirect transitions with a band gap energy of 1.96 eV and direct transitions with a band gap energy of 2.16 eV were determined from analysis of absorption data at room temperature. Dispersion of the refractive index is discussed in terms of the Wemple-DiDomenico single-effective-oscillator model. The refractive index dis...
