Figure 4. (A) STM image of the surface after deposition of > 1 ML Sn on Al(111) showing stripe structure (Sn-II phase) and abundant clusters on the surface (2.5 V, 50 pA, image size is 50 nm × 50 nm). (B) Atomic resolution STM image of Sn-II phase (16 mV, 900 pA). (C) Height profile along the white line in (B). (D) dI/dV spectra on the hill and valley of the stripe structure of Sn-II phase.
