Effect of substrate temperature on physical properties of In2O3:Sn films deposited by e-beam technique
Indium tin oxide (ITO) thin films were prepared by electron beam evaporation at different substrate temperatures. The structural studies were carried out by X-ray diffraction. Optical properties of the films were studied in the ultraviolet-visible-near infrared (UV-Vis-NIR) region (200 to 2500 nm). Electrical studies were carried out at room temperature of ITO films. The results showed that with increase in ... إقراء المزيد

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 ... إقراء المزيد

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

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 ... إقراء المزيد

Transparent conducting ZnO-CdO thin films deposited by e-beam evaporation technique

Transparent conducting ZnO-CdO thin films deposited by e-beam evaporation technique
Thin films of Zn1−x CdxO with x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5 at.% were deposited by electronbeam evaporation technique. It has been found that, for as-deposited films, both the transmittance and electrical resistivity decreased with increasing the Cd content. To improve the optical and electrical properties of these films, the effect of annealing temperature and time were ... إقراء المزيد

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

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 ... إقراء المزيد

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

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 ... إقراء المزيد
