Tip‐induced nanostructuring : Scanning with a STM tip very close to an electrode surface covered by a copper or palladium monolayer leads to a local alloy formation (see picture). The measurement of the tunneling resistance indicates that a point contact between the STM tip and electrode surface is sufficient for the alloying process.
