Abstract

The significance and reliability of very-LEED (VLEED) in revealing the details of a surface is demonstrated. This was done through the association of high resolution data, a suitable calculation code and reasonable modelling, as well as appropriate approaches in the calculations. This association enables us to classify the factors dominating the fine-structure features appearing on the VLEED spectra. Critical examination of the spectral sensitivity to the Cu(001)-O surface provides evidence that the VLEED are more highly sensitive to the bonding geometry than individual atomic-shift. The shapes of the fine-structure features are dominated by the elastic potential that determines the phase change of the diffracted beams. The inelastic potential has influence on the absolute intensity other than the shape of the I-V curve. It is justified that the inelastic damping is predominated by the outermost layer. Therefore, VLEED is such a technique that it is able to reveal nondestructive information from the overlayer integrating the bond forming and the behaviour of surface electrons.
