Abstract
A low-symmetry low-energy—electron-diffraction pattern observed at a fractional nitrogen-adatom coverage of 0.4 monolayer on W{001} is attributed to a structure composed of islands in which the surface-layer tungsten atoms are displaced to produce a contracted interatomic spacing. The model correlates well with other published data for this system.Keywords
