Structural, electrical and optical properties of indium tin oxide or ITO (In2O3:SnO2) thin films on different substrates are investigated. A 100-nm-thick pre-deposited zinc oxide (ZnO) buffer layer is utilized to simultaneously improve the electrical and optical properties of ITO films. High purity ZnO and ITO layers are deposited with a radio frequency sputtering in argon ambient with plasma p...

Improvement in the water stability and other related functional properties of thin (<50 μm) kafirin protein films was investigated. Thin conventional kafirin films and kafirin microparticle films were prepared by casting in acetic acid solution. Thin kafirin films cast from microparticles were more stable in water than conventional cast kafirin films. Treatment of kafirin microparticles with he...

In this study, the structural and nanomechanical properties of Cu₂O thin films are investigated by X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and nanoindentation techniques. The Cu₂O thin films are deposited on the glass substrates with the various growth temperatures of 150, 250 and 350 °C by using radio frequency magnetron sputtering. The XRD re...

Undoped and Mg-doped ZnO thin films were deposited on Si (111) and quartz substrates by using the sol–gel method. Microstructure, surface topography and water contact angle of the thin films have been measured by X-ray diffraction (XRD), an atomic force microscope (AFM) and water contact angle apparatus, respectively. The XRD results show that all the thin films are polycrystalline with a hexag...

Bi2Te3)0.2(Sb2Te3)0.8 compounds thin films on glass substrates are fabricated by a flash evaporated deposition method. In order to enhance the performance of the thin films, annealing in an argon atmosphere is carried out for 1 hour in the temperature range from 200 to 400 C. The structure of the thin films, in terms of homogeneity and crystalline quality, is investigated by means of x-ray mapp...

Oral films, a promising novel drug delivery system, are a strip of single or multilayered, mucoadhesive or non-mucoadhesive, thin polymeric films that are intended to deliver active therapeutic moieties either locally or systemically in oral cavity through sublingual, buccal, palatal, or gastrointestinal absorption [1-3]. In general, films are known by several names including but not limited to...

The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface morphology of SnO2 films was analyzed by the scanning electron microscopic (SEM) studies. The FT-IR spectrum exhibits the strong presence of SnO2. The optical properties of the...

In this paper, the transparent conductive aluminum-doped zinc oxide (ZnO: Al, AZO) thin films with different annealing conditions are studied. The AZO thin films were prepared on the Coring glass substrate by RF magnetron sputtering. The AZO thin films were annealed in atmosphere of vacuum and hydrogen at temperatures from 100 to 400°C in steps of 100°C for 1 min, respectively, to investigate t...
