In this study, structural properties of the Zn In Se (ZIS) thin films deposited by thermal evaporation method were investigated. The as-grown and annealed ZIS films were found in polycrystalline structure with the main orientation in (112) direction. The compositional analysis of the films showed that they were in Zn-rich behavior and there was a slight change in the elemental contribution to the structure with annealing process. Raman analysis was carried out to determine the crystalline structure and the different vibration modes of ZIS thin films. According to these measurements, the highest Raman intensity was in the LO mode which was directly proportional to the crystallinity of the samples. The atomic force microscopy (AFM) analyses were done in order to obtain detailed information about the morphology of the thin film surface. The surface of the films was observed as nearly-smooth and uniform in as-grown and annealed forms. X-ray photoelectron spectroscopy (XPS) measurements were analyzed to get detailed information about surface and near-surface characteristics of the films. The results from the surface and depth compositional analyses of the films showed quite good agreement with the energy dispersive X-ray spectroscopy (EDS) analysis.

This work presents our investigations of mezomorphic properties of two polymorphic liquid crystals, namely, 4-nonyloxy-4-butoxyphenyl benzoate and N-(-4-heptyloxybenzylidene-4-butylaniline) in a wide temperature range, particularly, in the phase transition regions. By means of an original Experimental method. the heterophase regions and also the phase transition temperatures have been determined for these materials with high accuracy. These phase transition intervals have been analyzed using a mean field mo...
CRITICAL BEHAVIOR OF THE SPECIFIC HEAT IN THE VICINITY OF THE TRANSITION TEMPERATURE FOR S-TRIAZINE
Kurt, M.; Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2009-04-10)
The critical behavior of the specific heat is studied in s-triazine (C3N3H3). Using the experimental data for the C-P, the temperature dependence of the specific heat is analyzed according to a power-law formula and the values of the critical exponent for C-P are extracted in the vicinity of the transition temperature (T-C=198.07K).
Investigation of inse thin film based devices
Yılmaz, Koray; Parlak, Mehmet; Department of Physics (2004)
In this study, InSe and CdS thin films were deposited by thermal evaporation method onto glass substrates. Schottky and heterojunction devices were fabricated by deposition of InSe and CdS thin films onto SnO2 coated glass substrates with various top metal contacts such as Ag, Au, In, Al and C. The structural, electrical and optical properties of the films were investigated prior to characterization of the fabricated devices. The structural properties of the deposited InSe and CdS thin films were examined t...
Structural and dynamical properties of liquid Pd-Ag alloys
Kart, HH; Tomak, Mehmet; Uludogan, M; Cagin, T (World Scientific Pub Co Pte Lt, 2004-06-30)
Structural and dynamical properties of Pd, Ag pure liquid metals and especially PdxAg1-x, alloys are studied by the molecular dynamics simulation. The effects of temperature and concentration on the liquid properties of PdxAg1-x, are analyzed. Sutton-Chen (SC) and Quantum Sutton-Chen (Q-SC) many-body potentials are used as interatomic interactions. The calculated diffusion constants and viscosities are in good agreement with the available experimental data and theoretical calculations. The coefficients of A...
CALCULATION OF VOLUME AS FUNCTIONS OF TEMPERATURE AND PRESSURE IN ICE I CLOSE TO THE MELTING POINT
Kilit, E.; Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2010-07-30)
We calculate in this study the volume of ice I as functions of temperature and pressure close to the melting point by analyzing the experimental data for the thermal expansivity. Using an approximate relation, the temperature dependence of the volume is calculated at 202.4 MPa from the thermal expansivity of ice I. The pressure dependence of the volume is also calculated at 252.3 K from the isothermal compressibility of ice I close to the melting point.
