    Notes: The electrochemical bath used for growing device-quality CIS (CuInSe2) thin films by co-deposition as well as layer-by-layer (LBL) deposition was characterised and optimised with respect to the film properties. The bath composition was varied by changing the Cu, In and Se ion concentrations in specific ratios in both co-deposition and LBL deposition. The film properties were analysed using techniques such as SEM (scanning electron microscopy), EPMA (electron probe microanalysis), AES (Auger electron spectroscopy) and XRD (X-ray diffraction). The structural, morphological and compositional properties of the films were characterised and their variation is attributed to the bath composition and growth conditions. © 1998 John Wiley & Sons, Ltd.

    Notes: Multilayers of ZrN/BN have been deposited on Si(100) using a double ion beam sputtering system. The multilayers have been characterized by transmission electron microscopy, Rutherford backscattering spectroscopy and Auger electron spectroscopy (AES) depth profiles in order to get a quantitative analysis of the components and contaminants in the different layers and at their respective interfaces. Factor analysis is used to deconvolute the different chemical states of the components and to identify secondary phases and compounds that determine the quality of the multilayer. Two secondary phases have been observed at the different interfaces: one is associated with the incorporation of oxygen, mainly in the zirconium layer, and leads to the formation of ZrNxOy. In addition we have observed that Ar bombardment during the AES depth profile leads to the formation of ZrBxNy in all the interfaces. © 1998 John Wiley & Sons, Ltd.

    Notes: For the present study we have considered powders made up of small particles (〈1 μm) coated with a uniform overlayer. Different models have been developed to predict the elemental compositions in this kind of sample by x-ray photoelectron spectroscopy (XPS) and absorption spectroscopies: electron energy-loss spectroscopy (EELS) and x-ray absorption spectroscopy (XAS). Isolated spherical or cubic particles, aggregated spherical particles and continuously layered models have been considered to take different possible textures of the samples into account. Theoretical curves have been compared to experimental data obtained for Al2O3/Al ultrafine powders made up of Al metal cores coated with an Al2O3 overlayer. The dependence of both photoelectron and absorption spectroscopy analysis on overlayer thickness and sample texture as a function of particle size is discussed. © 1998 John Wiley & Sons, Ltd.
