Surface structure and local bonding on the Si(111)-Ce surface
We used scanning tunnelling microscopy (STM) and photoelectron spectroscopy (PES) to study the cerium-induced (3 x 2) surface reconstruction of cerium (Ce) on Sn(111). Comparison with similar rare-earth-metal-induced low-coverage reconstructions on the Sn(111) surface reveals a similar nature of the chemical bond independent of the valence of the rare earth metal.
