  • Abstract
    Thin film model cathodes prepared as 200nm nominally thick sputter deposited coatings in many configurations of Sc, Sc2O3, Ba, BaO on W foil (0.05mm thick) were studied using photoelectron emission microcopy (PEEM) and thermionic emission microscopy (ThEEM) in a BauerTelieps style LEEM/PEEM.
