X-ray diffraction data, electron microscope and optical properties of cadmium sulfide nanoparticles were analyzed. It is shown that the value of the reduced effective mass of charge carriers in nanoparticles differs from bulk crystals. Changes of effective mass and "red shift" in values of band gap are explained by the occurrence of additional electronic potential in nanoparticles.

Optical characterization of CuIn5S8 crystals by ellipsometry measurements
IŞIK, MEHMET; Gasanly, Nizami (2016-04-01)
Optical properties of CuIn5S8 crystals grown by Bridgman method were investigated by ellipsometry measurements. Spectral dependence of optical parameters; real and imaginary parts of the pseudodielectric function, pseudorefractive index, pseudoextinction coefficient, reflectivity and absorption coefficients were obtained from the analysis of ellipsometry experiments performed in the 1.2-6.2 eV spectral region. Analysis of spectral dependence of the absorption coefficient revealed the existence of direct ban...
Optical characterization of Ga2SeS layered crystals by transmission, reflection and ellipsometry
IŞIK, MEHMET; Hasanlı, Nızamı (2015-07-10)
Optical properties of Ga2SeS crystals grown by Bridgman method were investigated by transmission, reflection and ellipsometry measurements. Analysis of the transmission and reflection measurements performed in the wavelength range of 400-1100 nm at room temperature indicated the presence of indirect and direct transitions with 2.28 eV and 2.38 eV band gap energies. Ellipsometry measurements were carried out in the 1.2-6.0 eV spectral region to get information about optical constants, real and imaginary part...
Optical properties of Cu3In5S9 single crystals by spectroscopic ellipsometry
Işık, Mehmet; Nasser, H.; Ahmedova, F.; Guseinov, A.; Hasanlı, Nızamı (2018-01-01)
Cu3In5S9 single crystals were investigated by structural methods of x-ray diffraction and energy dispersive spectroscopy and optical techniques of ellipsometry and reflection carried out at room temperature. The spectral dependencies of optical constants; dielectric function, refractive index and extinction coefficient, were plotted in the range of 1.2-6.2 eV from ellipsometric data. The spectra of optical constants obtained from ellipsometry analyses and reflectance spectra presented a sharp change around ...
Properties of Al2O3: nc-Si nanostructures formed by implantation of silicon ions into sapphire and amorphous films of aluminum oxide
Tetelbaum, D. I.; Mikhaylov, A. N.; Belov, A. I.; Ershov, A. V.; Pitirimova, E. A.; Plankina, S. M.; Smirnov, V. N.; Kovalev, A. I.; Turan, Raşit; Yerci, Selçuk; Finstad, T. G.; FOSS, SEAN (2009-02-01)
Photoluminescence, infrared Fourier spectroscopy, Raman scattering, transmission electron microscopy, and electron diffraction were used to study the luminescent, optical, and structural properties of aluminum oxide layers (sapphire and films of Al2O3 deposited on silicon) implanted with Si+ to produce silicon nanocrystals. It is established that, in both cases, a high-temperature annealing of heavily implanted samples brings about the formation of silicon nanocrystals. However, the luminescent properties o...
Intrinsic photoconductivity of P3HT films measured by time-resolved THz spectroscopy
Esentürk, Okan; Heilweil, Edwin J. (2007-12-01)
Intrinsic photoconductivities of P3HT polymers were measured and compared by using optical pump-THz probe spectroscopy. The charge carrier mobility shows a clear dependence on the molecular weight and dispersion index of the polymers.
