摘要： In a metallic structure including a metallic nano-chain with plasmon resonance absorption, a metallic nanoparticle forming the metallic nano-chain is formed in a circular, triangle, or rhomboid shape. The wavelength selectivity can be increased also by forming a closed region by mutually linking all of metallic nanoparticles that are mutually linked with bottlenecks. In a photodetector, a photodetection unit including a current detection probe, a nano-chain unit, and a current detection probe is arranged on a substrate. The nano-chain unit is a metallic structure with plasmon resonance absorption, where metallic nanoparticles are mutually linked with bottlenecks. Each current detection probe has a corner whose tip is formed with a predetermined angle, and this corner is arranged to face the tip of the nano-chain unit, i.e., a corner of the metallic nanoparticle. Photodetection with high wavelength selectivity is performed based on a change in the initial voltage of the current-voltage characteristic.

摘要： A metal structure capable of significantly increasing wavelength selectivity and polarization electivity for an incident light, and a production method thereof. First, a solid transparent substrate (glass substrate) (10) is cleaned and dried (S100). The surface of the substrate (10) is spin-coated with a positive electron lithography-use resist solution and then baked, and the resist solution is removed to form a resist thin film (20) on the substrate (10) (S200). A specified pattern is drawn on the resist thin film (20) with an electron beam, and the film is developed, rinsed and dried (S300). Then, metals such as chromium and then gold are formed sequentially on the substrate (10) by sputtering (S400). And, excessive resist materials are removed from the surface of the substrate (10) (S500), whereby metal nano-rod array (40) is completed. The metal nano-rod array (40) has a structure in which many metal nano-rods having their sizes precisely controlled are integrated on the substrate (10) at constant fine intervals and with their directions aligned in one axial direction.
