✦ Synopsis

Direct evidence that Nb and Cu atoms are associated with the nanocrystalline formation of Fe73.sSi13.sB9CulNb 3 was obtained using X-ray absorption fine structure (XAFS) measurements. XAFS results at the Cu K edge showed that the local structure around Cu atoms in Fe73.sSi~3.sBgCujNb 3 changes from amorphous to f.c.c, prior to the precipitation of b.c.c. Fe(Si). The local structure around Nb atoms retains its amorphous state up to the second crystallization temperature and subsequently changes to the F%B crystalline state after being annealed at the second crystallization temperature.

Oxygen interaction of CdS-based gas sens

Oxygen interaction of CdS-based gas sensors with different stoichiometric compositions was studied by X-ray photoelectron spectroscopy (XPS) and thermal-desorption mass spectroscopy observations combined with conductivity measurements. Three different types of film with different atomic ratios of Cd/S were used in the study of oxygen chemisorption in a low-temperature range between 300 and 570 K. Spray pyrolysis was used for the deposition of the films on glass substrates; XPS and energy dispersive spectroscopy of X-ray together with atomic force microscopy and scanning electron microscopy were used for the characterization of the composition and structure of the films. It was possible to distinguish different temperature ranges for the thermal desorption of the different adsorbed oxygen species. A comparison of the data from XPS and mass-spectroscopy observations with conductance measurements allows to conclude that metallic surface atoms are responsible for different interactions of oxygen species with CdS surfaces.
