Fig. 7: STM filled-state (group-IV related) cross-sectional images of GaInP within the blue outline of Fig. 1. The scan size is 26x20 atoms (??? ??? pixels). The image has been low-pass filtered (averaged) to reduce the noise and high-passed filtered to flatten the image and rotated. The atomic positions are labeled according to the same criteria used in Fig. 3. The open rectangle mark the dark atoms (Ga) while the open diamond marks the bright atoms (In).
