【Abstract】 small-angle x-ray diffraction study on Si/Co multilayer thin films has been undertaken .The big diffraction peaks of multilayer thin films with a less number of periods and a numbers of satellite peaks between the big peaks has been analyzed bydiffraction theory. For calculating the thickness of multilayer and single layer films ,a simple method with angles-difference of adjacent peaks was presented ,which reduced system error and located deviation and made data process simple. Also,The chemical state in Si/Co interface was analyzed by XPS .The results showed that therewere silicide there.更多还原
