Measurements were made of the Fermi surface and the underlying band structure of Sn/Cu(100)-(2√2 x 2√2)R45°. This phase was observed for a coverage of 0.60 to 0.65 monolayers. Its electronic structure was characterized by a free-electron-like surface band folded with the reconstruction periodicity. At variance with other surface phases of Sn on Cu(100), no temperature-induced phase transition was observed for this phase from 100K up to the desorption of Sn.
