    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： Provided is a plasmon resonance detector that can detect temperature change in optical devices, in which the metal structure having plasmon resonance absorption is used for the optical devices. A diode formed of a conductive substrate, an n-type semiconductor layer, an i-type semiconductor layer, a p-type semiconductor layer, an n electrode (negative electrode), a p electrode (positive electrode), an insulating film, or the like is used as a semiconductor device whose resistance value changes in accordance with temperature change. A nanochain formed by connecting a plurality of metal nanoparticles is disposed on this diode. When the nanochain is irradiated with light, the nanochain generates heat. The heat generated in the nanochain is conducted to the diode. The resistance value of the diode changes in accordance with temperature change, and thus this change is read, a temperature or an amount of heat generation of the nanochain is measured, and existence and strength of the plasmon resonance are detected.
