Research Abstract |
A new method for obtaining the interface structure of ultra-thin films on substrates from the analysis of X-Ray CTR scattering has been developed with a holographic method and iterative phase retrieval methods. In the method, inter-atomic layer distances, electron density and its distribution in each atomic layer are obtained for ultra-thin films on substrate. The results give valuable information on electronic states and crystal growth mechanisms.
