ELECTROCRYSTALLIZATION OF METALS AND MODERN NANOTECHNOLOGY

摘要

Nanostructures on solid surfaces with a lateral width of less than 10 nm can only be directly produced, i. e. without lithographic intermediate steps, by local electrodeposition of metals on foreign substrates using in situ Scanning Probe Microscopy as an atomic tool combined with appropriate polarization techniques of both the substrate and the probe. At present, 0D metallic nanoclusters on foreign metals, graphite, superconducting films, and semiconductors have been formed. Investigations on the electrochemical formation of 1D and 2D nanostructures by local electrocrystallization processes are in progress. Nanostructures on semiconductors and foreign metals are of great importance for nanoelectronic and nanomagnetic devices, respectively. Quantum phenomena are expected to occur in small nanoelectric devices even at room temperature.
