A misfit structure in the Co/Pt(111) system studied by scanning tunnelling microscopy and embedded atom method calculations
We have performed scanning tunnelling microscopy (STM) measurements of thin films of Co and CoPt alloys on Pt(111). In contrast to the interpretation of an earlier low energy electron diffraction investigation by Tsay and Shern [Surf. Sci. 396 (1998) 313] we find that the structure observed upon annealing a Pt(111) sample with a 2 ML (monolayer, ML) thick film of Co does not consist of a rotated C
