    摘要: This invention provides a method for constructing bridge including fine wires or point contacts producing a quanitized inter-electrode conductance, and provides a method for easily controlling the conductance of this bridge. Further, it aims to provide an electronic element using conductance control due to the bridge, fine wire or point contact formed between the electrodes. These objects are accomplied with an electronic element comprising a first electrode comprising a mixed electroconducting material having ion conductance and electron conductance, and a second electrode comprising an electroconducting substance, wherein the inter-electric conductance can be controlled. In another aspect, this invention is an electronic element formed by a bridge between electrodes, by applying a voltage between the electrodes so that the second electrode is negative with respect to the first electrode and movable ions migrate from the first electrode to the second electrode. In a third aspect, this invention is a method of controlling inter-electrode conductance comprising at least one of applying a voltage between the electrodes of the above electronic element so that the second electrode is negative with respect to the first electrode so that a bridge is formed between the electrodes due to the migration of movable ions from the first electrode to the second electrode, and reversing the inter-electrode polarity so that the bridge is thinned or disconnected.

    摘要: The invention provides a probe for use with a scanning tunneling microscope, a method of treating the probe, and a method of fabricating a nano-structure, which facilitates formation of a continuous nano-structure. The probe for the scanning tunneling microscope is formed of an Ag2S crystal having both ion conductivity and electron conductivity. Voltage and tunnel current are applied between the probe and a substrate in order to move movable Ag ions to thereby grow, on the tip end of the probe, a projection (mini chip) composed of Ag ions or Ag atoms. The polarity of the applied voltage is reversed after the growth of the projection in order to return the Ag ions or Ag atoms constituting the grown projection (mini chip) into the Ag2S crystal to thereby contract the projection. Thus, the probe can have a projection composed of Ag ions or Ag atoms and a regulated shape. Further, the movable ions or atoms of the mixed-conductive material are transferred onto the substrate so as to form a nano-structure on the substrate.
