Abstract
LEED intensity curves contain fine structure at low energies due to the interaction of pre-emergent beams with the surface potential barrier. Generally these regions of the spectra are avoided due to the difficulty in obtaining reliable data and fitting the spectra. We have recently developed computer programs that model the effect of the surface barrier potential on the I/V curves. These differ from our previous programs in that they interface to the Van Hove-Tong LEED package and so can be used to model the I/V curves from surfaces with more than one atom per unit cell. We have used these to model the surface reconstructions that occur when oxygen chemisorbs on Cu(001). We have found good agreement with the missing row model of Zeng et al [1]. We have also found strong evidence to suggest a c(2x2) structure intermediate between the clean surface and the missing row reconstruction.
