Structure of the CaF2(111) Surface and Its Change with Electron Bombardment Studied by Impact Collision Ion Scattering Spectroscopy (ICISS)

Souda, R. / Aono, M.

Abstract The clean annealed CaF2(111) surface has a F-terminated bulk-like 1×1 structure. The distance between the outermost F layer and the second Ca layer is O.80±0.08 Å, which is almost equal to a corresponding interlayer distance in bulk, 0.79 Å. When the surface is bombarded with energetic electrons, F ions are desorbed from the surface and F vacancies are formed at the surface. As the electron bombardment proceeds, F ions are completely removed from the surface and as a result the surface turns to a disordered Ca layer. These defective nonstoichiometric surfaces are restored to the initial ordered state by heating them in ultrahigh vacuum at temperatures as high as about 500°C.
