Abstract

Abstract

En 中文
We demonstrate how quantitative information on surface kinetics can be obtained from the intensity fluctuations in a diffraction experiment. As an example we have calculated the diffraction intensity time autocorrelation function from a surface consisting of fluctuating steps. Two different rate limiting atomic processes are considered as the source of the fluctuations. We show that the mechanism for equilibrium of a step can be distinguished by the characteristic time decay of the diffraction intensity autocorrelation function. In addition we discuss limits on experimental parameters necessary to observe the diffraction fluctuations.
