| 中文摘要 | Approximate methods have been examined in the context of dynamical reflection high-energy electron diffraction (RHEED) calculations using two-dimensional Bloch waves. These approximate methods include Bethe potentials, the utilization of the block structure of the scattering matrix and the perturbation treatment of anomalous absorption effects. It is shown that the use of Bethe potentials provides a very efficient and accurate means for dealing with evanescent waves and numerical examples show that the use of Bethe potentials speeds up the calculations typically more than 15 times. The other two methods examined are less powerful and the improvement in computation efficiency varies from 30 to 60%. It is found that in general the perturbation method for dealing with anomalous absorption effects does not work with high precision. |
