| Sumario: | In this study, electron diffraction patterns observed under high vacuum conditions for an SrTiO<sub>3</sub> surface were interpreted in detail while paying special attention to the features of inelastic effects. The surface of the SrTiO<sub>2</sub> was carefully prepared to enforce its termination with single domains of TiO<sub>2</sub> layers at the top. The inelastic patterns were interpreted using analytical models. Two types of Kikuchi lines are recognized in this paper: those which can be described with the Bragg law and those which appear due to surface wave resonance effects. However, we also discuss that there exists a formal connection between the two types of the Kikuchi lines observed. |
