Epitaxial NiSi2 films of less than 40 Å thickness have been grown on atomically clean Si(111) surfaces. Ion channeling and blocking have been used to determine the morphology and orientation of these films, as well as the strain resulting from the lattice mismatch with the Si substrate. The films are found to be continuous for Ni coverages above 5×1015 atoms/cm2. For all coverages the films are (111) oriented but rotated 180° around the surface normal with respect to the substrate. The NiSi2-Si(111) interface has been probed directly by the ion beam and is found to be well ordered and atomically abrupt.
