First Spectromicroscopy Tests at the Taiwan Synchrotron-Radiation Research-Center (Srrc) - Chemical and Topographic Microimaging of Layered Systems

The first photoelectron spectromicroscopy experiments at the new 1.3 GeV ultrabright X-ray source of SRRC have produced interesting results concerning chemical and topographic features in three types of systems: neuron networks grown on metal substrates, cleaved surfaces of high-quality single crystals of Bi2Ca2SrCu2Ox (BCSCO) and Au-covered GaSe. In the case of BCSCO, a general tendency to chemical homogeneity - extremely important for sophisticated spectroscopic applications - sharply conflict with occasional evidence of chemical-contrast features related to inhomogeneties in the Sr content. No chemical inhomogeneity was observed for the GaSe-Au case, in contrast to the lateral variations both in composition and in band bending previously found at submonolayer coverage.
