Abstract

original image

High-precision nanostructuring with an STM combined with electrodeposition of a reactive metal allows the creation of iron clusters in an ionic liquid. This type of structuring would not be possible in an aqueous solution. The image shows a ring of 48 iron clusters on an Au(111) electrode surface. The diameter of the ring is 120 nm and the average height of the clusters is 0.6 nm.
