The scanning photoelectron microscope (SPEM) on beam tine 2.2 at the Elettra synchrotron produces small spot XPS spectra from a sub-micron radiation microprobe. It is also capable of producing surface images in terms of the energy resolved photoelectron signal. This microscope has been used to study oxidation on polycrystalline tin and lead surfaces and the variations in reactivity between different crystallite surfaces. The diffusion of gold and silver films on polycrystalline metal surfaces has also been followed.

    The valence state of vanadium atoms in polycrystalline K4.3V6O16.2 is studied by x-ray photoelectron spectroscopy. By decomposing the V 2P3/2 peak into Gaussian components, the relative amounts of V5+, V4+, and V3+ ions in the polyvanadate are evaluated before and after Ar+ ion milling. The top...

    We have demonstrated resistance switching using polycrystalline HfO2 film with a Cu top electrode for nonvolatile memory applications and revealed the Cu diffusion into the HfO2 layer during the filament formation process. Resistive switching was clearly observed in the Cu/HfO2/Pt structure by...

    Phase-change optical memories are based on the astonishingly rapid nanosecond-scale crystallization of nanosized amorphous 'marks' in a polycrystalline layer. Models of crystallization exist for the commercially used phase-change alloy Ge2Sb2Te5 (GST), but not for the equally important class of...
