Structure of the Si(111)-CaF/sub 2/ interface
Journal Article

· Phys. Rev. Lett.; (United States)
The structure of the Si(111)-CaF/sub 2/ interface has been determined with medium energy ion scattering. Ca bonds to the Si substrate in a geometric arrangement virtually identical to CaSi/sub 2/. Half of the F atoms at the interface are missing; there is no F-Si bonding and the interface is charge neutral. The structure we find has not been considered previously and provides a natural explanation for the results of published photoemission studies.
