摘要：

Directional solidification of eutectics is a route to produce iso-oriented metallic single crystalline nanowires (NWs). Etching or electrochemical oxidation allows selective dissolution of either of the phases to produce NW arrays, isolated NWs, nanopore arrays and also derived structures by combining various process steps. A good understanding of the thermodynamics and the kinetics of the phase transformation and chemical reactions including electrodissolution, passivation, selective etching, complexing of reaction products and electrodeposition in the systems NiAl- X (X = Re, W, Mo), Ag-Cu and Fe-Au was reached. Functional devices based on these NWs, like high aspect ratio NW based STM tips, nanoelectromechanical systems (NEMS), NW pH sensors and sensor arrays were constructed.
