研究実績の概要 |
I have fabricated and characterized various plasmonic metasurfaces to achieve better photon control as proposed. Using colloidal lithography, I fabricated large-area Al nanoantennas with tunable plasmon resonances in a wide wavelength range. Further accurate resonance wavelength tuning was demonstrated by post-fabrication etching, which also provides more accessible enhanced near-fields and sensing volumes leading to better molecular sensitivity.The results were published in Scientific Reports. I also have collaborated with researchers from Northwestern University and demonstrated infrared spectroscopic biosensing with single-crystal ITO nanorod arrays. This work demonstrated the great potential of ITO as alternative plasmonic materials.

理由
Overall the project goes well. The original goal of the proposal was to achieve better photon control with moire superlattices and plasmonic metasurfaces. With this in mind, I modified the research content and plan a bit and proposed more efficient nanostructures:Al nanoantennas and ITO nanorods. Two journal papers have already been published in this project and the results were also presented in various domestic and international conferences. I will perform the rest proposal including the moire superlattices in the 2nd year of this project and I believe I will be able to finish this project on time and achieve the research goals.

今後の研究の推進方策 |
I have slightly modified the research content in order to achieve better results. This does not affect the original goal of this proposal - to achieve better photon control on the nanoscale for efficient light-matter interactions. I only chose to study different nanostructure with better performance. The nanostructures are also fabricated using the same techniques in the original proposal. I will continue to fabricate more efficient nanostructures with novel plasmonic materials. I will use these nanostructures to control photon-molecule interactions in the infrared for better sensors. I will also fabricate the moire superlattices as detailed in the original proposal and investigate their applications for infrared sensing.
