Abstract:
Deposition of polycrystalline Lead sulfide nano thin films onto Si and glass substrates at temperatures (200- 300 °C) was carried out by chemical spraying route using optimized preparative conditions. The XRD pattern confirmed the formation of PbS semiconducting films with orthorhombic structure. The electrical and optical properties of the nano crystalline thin films were studied aiming to better understanding for the electrical and opto-electrical properties of a hetrojunction with p-type Si. It was found that, the average grain size of PbS in the films was between 4 nm and 7 nm. The band ga

Abstract:
ZnO1-хSx alloys have attracted a special interest of researchers due to the possibility of controlled change of the band gap in a wide range from 3.37 eV (ZnO) to 3.68 eV (ZnS). This allows creating of effective UV photodetectors, electroluminescent devices, and others. The use of ZnO1-хSx buffer layers instead of ZnO can increase the conversion efficiency of thin-film solar cells based on CdTe, Cu(In, Ga)Se2 and Cu2ZnSnS4.

The objective of this work was to grow doped ZnO by spray pyrolysis at low temperature. This was achieved via the initial objective of growing ZnO in unhoped-for over a wide range of conditions, in order to understand the growth behaviour of ZnO from Zn(acac)2.H(_2)O and to establish the optimum growth procedure at high and low temperature. Various techniques were employed to characterize the films and thus determine the optimum growth conditions (i.e measurement of film thickness, resistivity, Hall coefficient.

Abstract:
Magnesium oxide seems to be a good candidate regarding its bulk properties: large band gap (7.8 eV), high thermal conductivity and stability and an alternative dielectric to silicon dioxide (SiO2) to reduce the electric field in capacitive networks. MgO, widely used as a substrate for high-temperature superconductor films deposition, has attracted much attention due to its low dielectric constant, low dielectric loss, and less mismatch with YBCO films. With a low dielectric loss, MgO shows a wide application in microwave devices. Due to its low refractive index, MgO is especially a suitable bu

The structure properties of ZnO thin films were characterized by X-ray diffraction（XRD）. The electric properties were analyzed by Hall-effect measurement. In this study , we deposited the CZO film at temperature of 600°C under using nitrogen (N2) and oxygen (O2) as the diversion of gas. As results of X-ray diffraction revealed that the CZO thin films had great crystallinity on the c-axis direction, and made the（002）peak shifted to higher a

Traditionally oxide films can be prepared by various processes, such as chemical vapor deposition, RF magnetron sputtering, sol-gel and spray pyrolysis. The spray pyrolysis presents some advantages, such as possibility of varying the film’s properties by changing
