A TiO2-based photocatalytic film on glass for self-cleaning purposes was prepared via sol-gel. This film exhibits similar physical and chemical properties, including; (1) surface composition and chemistry, (2) crystal phase and size, (3) UV transmission, and (4) surface roughness/morphology, as commercially available (CVD-based) films. In addition the sol-gel derived, laboratory films deposited on glass exhibits comparable, or in some cases better photocatalytic performance than the commercially available films on glass. Photocatalytic performance of the commercial and laboratory prepared films are determined and are discussed in context of their material properties/ characteristics. Furthermore films are reacted in model solutions (neutral, acidic, and basic) which in turn not only cause changes in the surface composition and roughness of the films, but also cause an increase in the photocatalytic performance.

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...
INVESTIGATION ON DEVICE CHARACTERISTICS OF n-CdS/p-Ag(Ga-In)Te-2 HETEROJUNCTION DIODE
Bayrakli, O.; Gullu, H. H.; Parlak, Mehmet (World Scientific Pub Co Pte Lt, 2018-07-01)
This work indicates the device properties of polycrystalline p-AgGaInTe2 (AGIT) thin films deposited on bare and ITO-coated glass substrates with thermal evaporation technique. Device characteristics of n-CdS/p-AGIT heterostructure have been analyzed in terms of current-voltage (I-V) for different temperatures and capacitance-voltage (C-V) measurements for different frequencies, respectively. The series and shunt resistances were determined from the analysis of parasitic resistance for high forward and reve...
INVESTIGATION OF CONDUCTIVITY CHARACTERISTICS OF Zn-In-Se THIN FILMS
Gullu, H. H.; Parlak, Mehmet (World Scientific Pub Co Pte Lt, 2020-01-01)
Zn-In-Se thin films were fabricated on the ultrasonically cleaned glass substrates masked with clover-shaped geometry by thermal evaporation of its elemental sources. Temperature-dependent conductivity characteristics of the films were investigated under dark and illuminated conditions. The semiconductor type of the films was found as n-type by thermal probe test. According to the van der Pauw technique, the dark electrical conductivity analyses showed that the variations of conductivity of unannealed and a...
Effects of glass substrate coated by different-content buffer layer on the quality of poly-Si thin films
Karaman, Mehmet; ÖZMEN, ÖZGE TÜZÜN; Sedani, Salar Habibpur; Ozkol, Engin; Turan, Raşit (Wiley, 2016-12-01)
In this work, polycrystalline silicon (poly-Si) thin films were fabricated by aluminum induced crystallization (AIC) technique. SiNx, deposited as a function of NH3/SiH4 ratio, and AZO (Al-doped ZnO) films on glass were used as a buffer layer between glass and Si film. The effect of buffer layer content on the crystallinity of poly-Si thin films was studied by Raman analysis which shows that fully crystallization without stress was achieved for all samples. Moreover, the preferred crystalline orientation an...
Indium tin oxide thin films elaborated by sol-gel routes: The effect of oxalic acid addition on optoelectronic properties
Kesim, Mehmet Tumerkan; Durucan, Caner (Elsevier BV, 2013-10-31)
Single layer indium tin oxide (ITO) thin films were deposited on glass using modified sol-gel formulations. The coating sols were prepared using indium (InCl3 center dot 4H(2)O) and tin salts (SnCl4 center dot 5H(2)O). The stable sols were obtained using ethanol (C2H5OH) and acetylacetone (C5H8O2) as solvents and by the addition of oxalic acid dihydrate (C2H2O4 center dot 2H(2)O) in different amounts. The effect of oxalic acid content in the sol formulation and post-coating calcination treatment (in air at ...
