(a) Typical STM image of a surface with mix phases of 4 × 4 and . The cross lines indicates the relative rotation of the orientation of the two phases. Panel (b) shows in the same image three domains marked by numbers 1–3, where different long range, domain boundary patterns can be recognized. The image sizes are (a) 30 nm×30 nm and (b) 50 nm×50 nm.
