Figure 1

(a) STM image of Ge(001) before Ir deposition (−1.5 V, 0.5 nA image size is 35 × 35 nm2). (b) STM image after the deposition of 0.01 ML Ir and annealed at 450 K (−0.55 V, 0.5 nA, image size is 145 × 145 nm2. Inset: −0.86 V, 0.2 nA, image size is 4 × 4 nm2). (c) STM image after the deposition of 0.3 ML of Ir and annealed at 450 K (0.50 V, 0.5 nA, image size is 145 × 145 nm2). (d) Close up on an Ir nanowire. A simple ball and stick model for an Ir nanowire is superimposed on the STM image (−0.86 V, 0.2 nA). (e) STM image of an array of Pt nanowires on a Ge(001) surface (−1.5 V, 0.5 nA, image size is 8 × 8 nm2) and (f) STM image of an array of Au-induced nanowires on a Ge(001) surface (−1.5 V, 0.2 nA, image size is 7.5 × 7.5 nm2).
