    • Adsorption site of alkali metal overlayers on Si(001) 2 × 1 

      Batra, I. P.; Ciraci, S. (1992)
      The alkali metal semiconductor interfaces are currently being investigated by a variety of tools. Most studies to date at half a monolayer coverage have shown preference for either a quasi-hexagonal (H) site or a long-bridge ...
    • Electronic structure of a Si delta-layer embedded in Ge(001) 

      Gulseren, O.; Ciraci, S. (Institute of Physics Publishing, 1991)
      Using the Green function formalism with layer orbitals we studied the electronic structure of a Si δ-layer in germanium. We found two-dimensional parabolic subbands near the band edges. This approach is extended to treat ...
