Abstract

The 1st photoelectron spectromicroscopy expts. at the new 1.3 GeV ultra-bright x-ray source of SRRC produced interesting results concerning chem. and topog. features in 3 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 chem. homogeneity - extremely important for sophisticated spectroscopic applications - sharply conflict with occasional evidence of chem.-contrast features related to inhomogeneities in the Sr content. No chem. inhomogeneity was obsd. for the GaSe-Au case, in contrast to the lateral variations both in compn. and in band bending previously found at submonolayer coverage. [on SciFinder(R)]
