Morphologies and optical properties of mixed tin oxysulfide produced by evaporation condensation of SnS

2018-10-05 17:33:54 Keywords Tin oxysulfide , Evaporation c, Nanowires, optical properties,
Morphologies and optical properties of mixed tin oxysulfide produced by evaporation condensation of SnS
The goal of the present study was to use the evaporation-condensation method of SnS to synthesize mixed novel tin oxysulfide nanostructures. Structural, morphological and optical properties of these nanomaterials were investigated. Synthesis was carried out in horizontal tube furnace using Au coated quartz and Si(100) substrates. The substrates were set along 1–25 cm from the centered alumina boat. The deposition ... Read more

Optical Properties of Nanocrystalline/Amorphous TiO2 Thin Film Deposited by rf Plasma Magnetron Sputtering

2018-10-02 08:10:55 Keywords TiO2 Thin Films, Rf magnetron, sputtering, optical properties,
Optical Properties of Nanocrystalline/Amorphous TiO2 Thin Film Deposited by rf Plasma Magnetron Sputtering
This work is a part of serious experimental efforts established on constructing multilayers based on TiO2 for industrial use in optical devices. Recognizing the structure and optical features of TiO2 single layer is very significant in designing optical devices and in constructing multilayers based on TiO2 layer for probable industrial requests. In this regard, rf plasma magnetron sputtering was employed ... Read more

p-Type transparent conducting copper-strontium oxide thin films for optoelectronic devices

p-Type transparent conducting copper-strontium oxide thin films for optoelectronic devices
p-Type thin films of copper-strontium oxide (Cu-Sr-O) have been deposited by e-beam evaporation technique on microscopic glass substrates. A study of optical, electrical and structural properties was performed on the thin films, varying temperature of annealing. Amorphous Cu-Sr-O films were obtained at low temperature. Partially polycrystalline films were obtained at high temperature of 550◦ C with transparency over 72% at ... Read more

Development of structural and optical properties ofWOx films upon increasing oxygen partial pressure during reactive sputtering

2018-09-02 21:49:36 Keywords WOx films, dc sputtering, Structural properties, optical properties,
Development of structural and optical properties ofWOx films upon increasing oxygen partial pressure during reactive sputtering
WOx films were prepared by reactive dc magnetron sputtering using tungsten target. Sputtering was carried out at a total pressure of 1.2 Pa using a mixture of argon plus oxygen in an effort to determine the influence of the oxygen partial pressure on structural and optical properties of the films. The deposition rate decreases significantly as the surface of the ... Read more

Optical and Electrical Properties of Tin-Doped Cadmium Oxide Films Prepared by Electron Beam Technique

2018-09-02 22:03:00 Keywords thin-films, Tin-Doped Cadmium Oxide, optical properties, electrical properties, Structural properties,
Optical and Electrical Properties of Tin-Doped Cadmium Oxide Films Prepared by Electron Beam Technique
Tin-doped cadmium oxide films were deposited by electron beam evaporation technique. The structural, optical and electrical properties of the films were characterized. The X-ray diffraction (XRD) study reveals that the films are polycrystalline in nature. As composition and structure change due to the dopant ratio and annealing temperature, the carrier concentration was varied around 1020 cm3, and the mobility increased ... Read more

Enhancement of the optical and electrical properties of ITO thin films deposited by electron beam evaporation technique

2018-09-02 22:27:35 Keywords ITO thin films, electron beam, optical properties, electrical properties, Structural properties,
Enhancement of the optical and electrical properties of ITO thin films deposited by electron beam evaporation technique
Indium tin oxide (ITO) is widely utilized in numerous industrial applications due to its unique combined properties of transparency to visible light and electrical conductivity. ITO films were deposited on glass substrates by an electron beam evaporation technique at room temperature from bulk samples, with different thicknesses. The film with 1500 ˚A thick was selected to perform annealing in the ... Read more

Effect of annealing and In content on the properties of electron beam evaporated ZnO films

2018-09-02 22:32:41 Keywords ZnO:In thin films, electron beam, optical properties, Structural properties, electrical properties,
Effect of annealing and In content on the properties of electron beam evaporated ZnO films
The effect of both annealing and In content on the properties of ZnO films prepared by electron beam evaporation were investigated. The evaporation was carried out at room temperature from bulk samples prepared by sintering technique. X-ray diffraction showed that the structure of ZnO-In2O3 films depends on both the In content and annealing temperature. Amorphous, highly transparent and relatively low ... Read more
