We present a mathematical approach to the experimental data recorded via Fourier transform-infrared spectroscopy regarding the influence of the concentration of the antimicrobial peptide gramicidin S (GS) on the thermotropic phase transition of the dipalmitoylphosphatidyl-glycerol (DPPG) lipid bilayer membrane in DPPG/GS systems. The model is based on the influence of the GS concentration on the parameters of a nonlinear damped oscillator, which models the CH2 symmetric stretching band.

Effect of temperature and isomorphic atom substitution on optical absorption edge of TlInS2xSe2(1-x) mixed crystals (0.25 <= x <= 1) Hasanlı, Nızamı (Wiley, 2010-05-01) The optical properties of the TlInS2xSe2(1-x) mixed crystals (0.25 <= x <= 1) have been investigated through the transmission and reflection measurements in the wavelength range of 400-1100 nm. The optical indirect band gap energies were determined by means of the analysis of the absorption data. It was found that the energy band gaps decrease with the increase of selenium atoms content in the TlInS2xSe2(1-x) mixed crystals. The transmission measurements carried out in the temperature range of 10-300 K reve...
Effects of annealing on structural, electrical and optical properties of AgGa(Se0.5S0.5)(2) thin films deposited by using sintered stoichometric powder KARAAĞAÇ, HAKAN; Parlak, Mehmet (Wiley, 2009-04-01) The structural, electrical and optical properties of AgGa(Se0.5S0.5)(2) thin films deposited by using the thermal evaporation method have been investigated as a function of annealing in the temperature range of 450-600 degrees C. X-ray diffraction (X-RD) analysis showed that the structural transformation from amorphous to polycrystalline structure started at 450 degrees C with mixed binary phases of Ga2Se3, Ga2S3, ternary phase of AgGaS2 and single phase of S. The compositional analysis with the energy disp...
Effect of isomorphic atom substitution on the refractive index and oscillator parameters of TlInS2xSe2(1-x) (0.25 <= x <= 1) layered mixed crystals Hasanlı, Nızamı (Wiley, 2010-11-01) The optical properties of TlInS2xSe2(1-x) mixed crystals (0.25 <= x <= 1) have been studied at room temperature through the transmittance and reflectivity 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: oscil...
Effect of crystal disorder on linewidth of the Raman modes in GaS1-xSex layered mixed crystals Hasanlı, Nızamı (Wiley, 2003-01-01) The linewidths of Raman-active intralayer compressional modes in GaS1-xSex layered mixed crystals (0 less than or equal to x less than or equal to 1) have been measured in the 10-300 K temperature range to study the anharmonic effect as a function of compositional variation and temperature. It was found that the anharmonicity increases with an increase in substitutional disorder. The cubic (three-phonon) processes with energy conservation is responsible for the anharmonic contribution to the broadening of t...
Influence of ion implantation on structural and photoconductive properties of Bridgman grown GaSe single crystals KARABULUT, ORHAN; Parlak, Mehmet; Turan, Raşit; SERİNCAN, UĞUR; Akınoğlu, Bülent Gültekin (Wiley, 2006-03-01) The structure and temperature dependent spectral photoconductivity of as-grown and N-and Si-implanted GaSe single crystals have been studied. It was observed that post-annealing results in a complete recovery of the crystalline nature that was moderately reduced upon implantation. The band edge is shifted in the implanted sample which is attributed to the structural modifications and continuous shallow levels introduced upon implantation and annealing. Our calculations showed that the trap density is increa...
