Figure 2: A: Sulphur adsorption on 0.2 ML O(21)-Cu(110) (Exposure approx. 61012 atoms/cm2). The dark stripes are the surface oxide stress domains, bright patches and lines appear upon S adsorption (140140 nm²; Ubias: -500 mV, It: 70 pA). B: High-resolution image of a similar preparation as in A (12.314.9 nm²; Ubias: 300 mV, It: 100 pA).
