| Outline of Final Research Achievements |
In this research, we explored a new plasmonic material called a high-entropy alloy, which is made of five or more metals, and succeeded in finding a material that can generate stronger light. Furthermore, in the photodetector, we constructed a thermopile structure in which a large number of thermoelectric elements were connected in series, and found that the sensitivity of the detector was improved. We also developed a light source. Conventional light sources have a large divergence angle, making it difficult to efficiently introduce light to a detector. In particular, it is important to condense light by controlling light radiation without using optical elements such as lenses. In this study, we performed radiation control based on a metalens structure and found that light could be focused. Through the above clinical trials, we succeeded in establishing the elemental technology for constructing P-Nose.
