چکیده
ZnO thin films were successfully deposited via spray pyrolysis technique over various substrates, including glass, silicon, and mesoporous silicon (PSi). The effect of substrate type on the surface morphological, structural, electrical properties film was investigated. Scanning Electron Microscopy confirms morphology meso-PSi displays morphologies ZnO. (ZnO/PSi) heterojunction shows a porous layer with large area by comparison to other structures. patterns X-ray Diffraction exposed that have hexagonal wurtzite polycrystalline structure. Ultraviolet (UV) metal-semiconductor-metal photodetectors been fabricated UV photodetector showed much higher photocurrent than

Cadmium Oxide Thin Films Deposited by a Simplified Spray Pyrolysis Technique for Optoelectronic Applications
Cadmium oxide thin films were fabricated on glass substrates by a simplified and low cost spray pyrolysis technique at different substrate temperatures. The X-ray diffraction study showed that irrespective of substrate temperature all the films exhibits a preferential orientation along the (1 1 1) plane. The values of crystallite size were found to be in the range 20.72 – 29.6 nm. The perce...

Preparation and growth of SnS thin film deposited by spray pyrolysis technique
In this paper thin films of tin sulfide (SnS) were deposited on the glass substrates using spray pyrolysis method with the substrate temperatures in the range of 400–600℃, keeping the other deposition parameters constant. In this work the characteristic of SnS thin films investigated. The XRD pattern and optical transmittance of thin films also are discussed. With the change in concen...
متن کاملThe effect of Ga-doping on the structural and optical properties of ZnO thin films prepared by spray pyrolysis
In this research, zinc oxide thin films with gallium impurity have been deposited using the spray pyrolysis technique. The structural and optical properties of these films are investigated as a function of gallium doping concentrations. The ZnO and ZnO:Ga films grown at a substrate temperature of 350 ºC with gallium doping concentrations from 1.0 to 5.0.%. The XRD analysis indicated that ZnO f...
