Figure 2From: Nickel-containing nano-sized islands grown on Ge(111)-c(2 × 8) and Ag/Ge(111)-(√3 × √3) surfacesFilled-state STM image taken after deposition of 0.1 ML Ni onto Ag/Ge(111)-√3 × √3 surface at RT. The image size is 80 × 80 nm2, and the bias voltage is -1.6 V. Inset: small-scale (24 × 22 nm2) image showing that clusters are randomly distributed on the surface.Back to article page
