Figure 1. Nonlocal and local manipulation of toluene on the Si(111)-7 × 7 surface at room temperature.

Figure 1

STM images (21 × 21 nm, +1 V, 100 pA) of toluene on Si(111)-7 × 7 taken before (a) and after (b) a charge injection (+2.7 V, 200 pA, 10 s) at location ‘X'. High resolution STM images (2.5 × 2.5 nm, +1 V, 100 pA) of toluene on Si(111)-7 × 7, taken before (c) and after (e) a charge injection (+1.6 V, 750 pA, 7 s) directly into the toluene molecule (dark spot) at location ‘X'. (d) Schematic diagram of a molecule binding to a restatom and adatom site. Time-trace (f) of the STM tip height above the molecule during the injection of C and E. (g) The probability per electron (α) as a function of injection voltage for a toluene molecule subject to manipulation (diffusion/desorption) by direct charge injection into the molecule.
