Hall Measurement System

Silver doped Indium sulphide thin films with different [Ag/In] molar ratio concentrations (0, 0.9, 1.0, 1.1) were deposited on glass substrates using chemical bath deposition method. The structural, morphological, optical and electrical properties are characterized using XRD, EDAX, SEM, AFM, spectrophotometer and Hall measurement system, respectively. Kramers-Kronig method was used to obtain optical constants of the films. It is found that Ag can change physical properties of Indium sulfide thin films, depending on the Ag concentration. XRD results show the incorporation of Ag concentration did not change the structure of In2S3. Doped films had rough surfaces. As the [Ag/In] molar ratio increased, conductivity increases and optical direct band gap energy decreases from 2.75 to 2.38 eV.

In the present work we prepared conducting and transparent thin films ZnO with different solution concentrations by pyrolysis spray technique on glass substrates. These films are obtained starting from solution of zinc acetate dehydrate [Zn(CH3COO)2.2H2O] dissolved in methanol, at substrate temperature fixed T =350°C with a concentration of solution vary from 0.05-0.2 M. Our interest is on the investigation of solution concentration on the structural and optical properties of these films. The X-ray diffraction (XRD) results showed that the synthesized ZnO films are polycrystalline with preferred orientation along the (002) plane. The optical films characterization was carried out by the UV-Visible transmission. The optical gap and films disorder were deduced from the absorption spectra, The values of optical band gaps vary between 3.24 and 3.43 eV.

Tin oxide films were deposited on glass substrates by reactive and non reactive r.f. sputtering using different types of targets corresponding to various Sn/F atomic ratio: hot pressed Sn–SnF2or SnO2–SnF2mixtures, ceramics obtained by casting either an aqueous SnO2–SnF2slurry or a suspension of tin oxide in molten tin fluoride. The samples were prepared in oxygen-argon gas mixtures in which the oxygen concentration was varied from 0 mole % up to 30 mole% depending on the target. The optical and electrical properties of the obtained thin films have been studied and compared to those of the films obtained by spray technique.

Polycrystalline CuInS\(_{2}\) (CIS) absorber films for solar cells were prepared by spray pyrolysis of aqueuos solution of copper chloride, indium chloride and thiourea onto heated glass substrates. By optimizing the spray parameters, such as reducing/increasing the temperature of the substrate and molar ratio of Cu/In in the spraying solution, the optical characteristics of films, which are well matched to the solar spectrum, were identified. In all cases, those CIS thin films were of p-type conductivity. Transmission measurements were performed to examine the optical properties of the films; the absorption coefficient and the optical band gap of the films were calculated by transmission spectra. The absorption spectra of the films showed that this compound is a direct band gap one and its gap varied between 1.30 - 1.78 eV. Those thin films were analyzed by X-ray diffraction in order to understand the effect of layers structure on their optical properties.

AbstractConditions necessary for the reproducible deposition of pristine In2S3 thin films on TO-glass substrates by low temperature solution deposition have been identified. Baths containing carboxylic acids yield adherent, specular and crystalline films, within a defined pH range, dependent on the particular acid employed. Films have been characterised by XRD, SEM, XPS and electronic spectroscopy. As–deposited films were found to crystallise as tetragonal β-In2S3, no evidence for incorporation of hydroxy-indium species was found by XPS measurements.

AbstractThin films of lead oxide were synthesized by cost effective spray pyrolysis technique at different substrate temperatures on glass substrates. Effect of substrate temperature on the growth mechanism and physical properties of the films was investigated. All the films were polycrystalline in nature with tetragonal structure corresponding to α-PbO. The films coated at 225 °C and 275 °C were (1 0 1) oriented, while the films deposited at 325 °C and 375 °C were (0 0 2) oriented. Above 375 °C, the pure tetragonal nature deteriorated and the peaks corresponding to orthorhombic phase were observed. The band gap value was found to be in the range of 2.3 to 2.62 eV. All the films had a resistivity of the order of 103 ohm-cm. A minimum resistivity of 0.0191 × 103 ohm-cm was obtained for the film coated at 325 °C. The activation energy increased with increase in substrate temperature.
