Abstract
Long silver fine wires have been successfully produced by approaching or contacting an electrically biased metal tip onto silver sheet covered with silver iodide (AgI) and subsequently retracting the tip. Silver iodide which is an ionic conductor acted as a source of supply of silver atoms even at room temperature. For the diameter of sub-micrometer level, the long wires of tens of micrometer length have been formed. Moreover, nanowires showing conductance quantization have been formed. Conductance measurements of the silver nanowire were performed at a modulation bias voltage, because offset voltage appeared in the silver iodide covered silver sheet sample. This method will be applied in investigating the property of carrier transport in long metal nanowire.
