✦ Synopsis
The authors review the correlated thermal diffuse scattering (CTDS) as a semi-direct tool for surface structure analysis. The strong vibrational correlation between very near-neighbor atoms induces broad features in the thermal diffuse scattering of diffraction. The broad features, which were paid little attention in crystallography, are the subject of CTDS. Only the short-range arrangement of neighbor atoms is reflected in CTDS so that one can treat CTDS as a kinematical diffraction, even with surface-sensitive electron diffraction. Thus the surface structure is semi-directly obtained by means of the kinematical analysis based on the Fourier transformation.
