In this study, N-doped ZnO thin films were fabricated by oxidation of ZnxNy films. The ZnxNy thin films were deposited on glass substrates by pulsed filtered cathodic vacuum arc deposition (PFCVAD) using metallic zinc wire (99.999%) as a cathode target in pure nitrogen plasma. The influence of oxidation temperature, on the electrical, structural and optical properties of N-doped ZnO films was investigated. P-type conduction was achieved for the N-doped ZnO obtained at 450 degrees C by oxidation of ZnxNy, with a resistivity of 16.1 Omega cm, hole concentration of 2.03 x 10(16) cm(-3) and Hall mobility of 19 cm(2)/Vs. X-ray photoelectron spectroscopy (XPS) analysis confirmed the incorporation of N into the ZnO films. X-ray diffraction (XRD) pattern showed that the films as-deposited and oxidized at 350 degrees C were amorphous. However, the oxidized films in air atmosphere at 450-550 degrees C were polycrystalline without preferential orientation. In room temperature photoluminescence (PL) spectra, an ultraviolet (UV) peak was seen for all the samples. In addition, a broad deep level emission was observed. (C) 2011 Elsevier B. V.

In this work, structural and temperature dependent optical properties of thermally evaporated CdS thin films were investigated. X-ray diffraction, energy dispersive spectroscopy and Raman spectroscopy experiments were carried out to characterize the thin films and obtain information about the crystal structure, atomic composition, surface morphology and vibrational modes. Temperature-dependent transmission measurements were performed in between 10 and 300 K and in the spectral range of 400-1050 nm. The anal...
Structural, optical and magnetic properties of Zn1-xCoxO thin films prepared by spray pyrolysis
BACAKSIZ, EMİN; AKSU, SERHAT; Basol, B. M.; Altunbas, M.; Parlak, Mehmet; Yamnaz, E. (Elsevier BV, 2008-09-01)
A series of Co-doped ZnO films were fabricated by a spray pyrolysis method. The X-ray diffraction patterns of the films showed that the undoped and Co-doped ZnO films exhibit wurtzite crystal structure. Surface morphology of the films obtained by scanning electron microscopy reveals that pure ZnO film has the hexagonal shaped microrods. The introduction of Co content in the structure did not affect the surface morphology of the films significantly. Magnetic hysteresis loops were observed at room temperature...
Structural and optical characteristics of thermally evaporated TlGaSe2 thin films
Isik, M.; KARATAY, AHMET; Hasanlı, Nızamı (2022-02-01)
The present paper reports the structural and optical properties of thermally evaporated TlGaSe2 thin films. X-ray diffraction pattern of evaporated film presented two diffraction peaks around 24.15 and 36.00° which are associated with planes of monoclinic unit cell. Surface morphology of the TlGaSe2 thin films was investigated by scanning electron and atomic force microscopy techniques. Although there was observed some ignorable amount of clusters of quasi-spherical shape in the scanning electron microscope...
Performance of polylactide against UV irradiation: Synergism of an organic UV absorber with micron and nano-sized TiO2
CAN, ULAŞ; Kaynak, Cevdet (SAGE Publications, 2020-08-01)
The main purpose of this study was to investigate mechanical and thermal performance of polylactide specimens against UV irradiation; first when only adding benzotriazole benzotriazole-based organic UV absorber (UVA), micro (200 nm) and nano (50 nm) sized titania (TiO2) particles alone, and then to reveal possible synergism when they are added together. Compounds were prepared by twin-screw extruder melt mixing, while the 2 mm thick specimens were shaped by compression molding. Specimens were exposed to UV ...
Structural and optical properties of Zn-In-Te thin films deposited by thermal evaporation technique
Gullu, H. H.; Bayrakli, O.; CANDAN, İDRİS; COŞKUN, EMRE; Parlak, Mehmet (2013-07-25)
Annealing effects on structural and optical properties of the thermally evaporated Zn-In-Te(ZIT) thin films have been investigated. The structural and the compositional analyses were carried out by means of X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDXA). The as-grown and annealed ZIT films had polycrystalline structure and the preferred orientation changed from (220) to (112) direction with increasing annealing temperature. The optical properties and constants were determined by transmi...
