Figure 3

The green shaded area marks a narrow patch of the B-2✓3Sn phase. The Sn tetramers of the 2✓3Sn and 4✓3Sn structures are highlighted by circles. Large circles mark the outward-relaxed atomic protrusions and smaller circles the inward-relaxed atomic features. Scanning parameters are Vs=1 V, It=0.2 nA. The scale bar is 1 nm. Mirror plane and glide plane symmetries are indicated on the right.
