| Outline of Final Research Achievements |
It was shown that simple “photonic nanofabrication” beyond the diffraction limit of light could be a new application for plasmon resonance. One of the important factors for the nanofabrication is “high efficiency,” and it was found that efficiency can be improved by combining particles that easily collect light as “antennae”. Another important factor is the abundance of materials that can be used, and it was found that the variety of materials can be increased by a relatively simple method, “galvanic replacement”. Furthermore, while plasmon resonance can only occur with highly conductive materials such as metals, it was found that “photonic nanofabrication” using a similar resonance phenomenon is possible with semiconductors, which are not very conductive.
