Reversible phase transformation and doubly-charged anions at the surface of simple cubic RbC60
Roberto Macovez, Andrea Goldoni, Luca Petaccia +3
The simple cubic phase of a RbC60 thin film has been studied using photoelectron spectroscopy. The simple cubic-to-dimer transition is found to be reversible at the film surface. A…
O- and H- induced surface core level shifts on Ru(0001): Prevalence of the additivity rule
S. Lizzit, Y. Zhang, K. L. Kostov +4
In previous work on adsorbate-induced surface core level shifts (SCLSs), the effects caused by O atom adsorption on Rh(111) and Ru(0001) were found to be additive: the measured shi…
Electronic structure and molecular orientation of a Zn-tetra-phenyl porphyrin multilayer on Si(111)
C. Castellarin Cudia, P. Vilmercati, R. Larciprete +13
The electronic properties and the molecular orientation of Zn-tetraphenyl-porphyrin films deposited on Si(111) have been investigated using synchrotron radiation. For the first tim…
Characterization of high-quality MgB2(0001) epitaxial films on Mg(0001)
Luca Petaccia, Cinzia Cepek, Silvano Lizzit +4
High-grade MgB2(0001) films were grown on Mg(0001) by means of ultra-high-vacuum molecular beam epitaxy. Low energy electron diffraction and x-ray diffraction data indicate that th…
Mechanism of formation of a 2D binary alloy
L. Ottaviano, G. Profeta, L. Petaccia +4
Direct comparison of scanning tunneling microscopy and high resolution core level photo-emission experiments provides a rationale for the mechanism of formation of a two dimensiona…
