Optical constants of layered structured Ga0.75In0.25Se crystals from the ellipsometric measurements
IŞIK, MEHMET; ÇETİN, ŞABAN; Hasanlı, Nızamı; ÖZÇELİK, SÜLEYMAN (2012-05-01)
We have carried out the spectroscopic ellipsometry measurements on Ga0.75In0.25Se single crystals in the 1.2-6.0 eV spectral range at room temperature. The optical constants, real and imaginary parts of the dielectric function, refractive index and extinction coefficient, were found as a result of analysis of ellipsometric data. The critical point analysis of the second derivative spectra of the dielectric function revealed four interband transition structures with critical point energy values of 3.19, 3.53...
Optical properties of TlGa(SxSe1-x) 2 layered mixed crystals (0=x=1): Absorption edge and photoluminescence study at T=10 K
Hasanlı, Nızamı (Springer Science and Business Media LLC, 2018-09-01)
Transmittance measurements of layered mixed crystals were performed in the 1.80-2.80 eV photon energy range at . Band-gap energies of the studied crystals were estimated by means of the derivative spectra of transmittance and photon energy dependence of absorption coefficient. The compositional dependence of direct band-gap energy at revealed that as sulphur (selenium) composition is increased (decreased) in the mixed crystals, the direct band-gap energy increases from 2.19 eV () to 2.67 eV (). Photolumines...
Optical properties of TlGaSeS layered single crystals
Güler, Işıkhan; Hasanlı, Nızamı (2007-12-01)
The optical properties of TlGaSeS layered single crystals have been investigated by measuring the transmissions and the reflections in the wavelength region between 400 and 1100 nm. The optical indirect transitions with a band gap energy of 2.27 eV and direct transitions with a band gap energy of 2.58 eV were found by means of the analysis of the absorption data at the room temperature. The rate of change of the indirect band gap with temperature, that is, gamma = -3.2 x 10(-4) eV/K, was determined from the...
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...
