Comparison of the Quasidynamical and Tensor LEED Approximation for LEED Intensity Spectra from a Reconstructed Surface

Bickel, N. / Heinz, K. / Landskron, H. / Rous, P. J. / Pendry, J. B. / Saldin, D. K.

Abstract The quasidynamical and Tensor LEED approximations of intensity spectra are compared to each other and to full dynamical data. Both approximations save considerable computer time. Tensor LEED approaches exact data more closely when starting from a close enough reference structure. On the other hand the quasi dynamical method puts no restrictions for an inspection of a larger parameter space. A combination of both methods is therefore suggested for optimization of computational efforts. Finally full dynamical and approximative results are compared to experimental data from reconstructed c(2×2) W(100).
