Abstract
A new template-assisted step-electrochemical method for fabricating metal-chalcogenide-based mixed conductors, is discussed. This method is applicable to forming Ag/Ag2S heteronanowire arrays (HNAs) that are advantageous for assembling nanoswitching devices. An ordered Ag/Ag2S HNA can be grown inside the pores of an anodic aluminum oxide (AAO) membrane with step-electrochemical reactions. It was observed that the growth of Ag 2S nanowires is dependent on an electrochemical sulfurization process confined by the AAO pores. The electric transport and switching behavior of the Ag/Ag2S HNA-filled AAo membrane was investigated by mechanical contact with a normal tungsten probe tens of micrometers in size. Electrical nanoswitching can be achieved by using an Ag/Ag2S heterostructure, whereas, HNAs of ionic and/or mixed conductors can also be applied in novel nano-electrochemical devices for sensors, fuel sells, and batteries.
