    • The method for producing a surface enhanced infrared absorption sensor of the invention is characterized by: adsorbing metallic nanoparticles dispersed in a solution on a surface of a substrate, or allowing the adsorbed metallic nanoparticles to be grown in a solution, thereby forming a film; applying infrared light to the substrate from the side thereof opposite to the side on which the metallic nano-thin film is disposed; detecting evanescent waves exuding from the substrate; and regulating a surface enhanced infrared adsorption activity while monitoring surface enhanced infrared adsorption signals in situ, whereby the metallic nano-thin film is grown in the form of flat and discontinuous islands. According to the method, there is provided a production technique for a surface enhanced infrared absorption (SEIRA) sensor having a higher sensitivity and more excellent in the reproducibility.

    • 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.
    • 本发明提供了一种用于扫描隧道显微镜的探针,一种处理该探针的方法,以及一种有助于形成连续纳米结构的纳米结构的制造方法。 用于扫描隧道显微镜的探针由具有离子传导性和电子传导性的Ag 2 S晶体形成。 电压和隧道电流施加在探针和衬底之间,以移动可移动的Ag离子,从而在探针的尖端上生长由Ag离子或Ag原子组成的突起(微型芯片)。 在投影生长之后,施加电压的极性反转,以将构成生长的突起(微型芯片)的Ag离子或Ag原子返回到Ag2S晶体中,从而使投影收缩。 因此,探针可以具有由Ag离子或Ag原子组成的突起和调节形状。 此外,将混合导电材料的可移动离子或原子转移到衬底上,以在衬底上形成纳米结构。
