2025 Activity Report vol.1:Shizuoka University

Activity Report of Open Application Program 2025 vol.1 (Course A)

Exchange program related to research and development of silicon photodetector with surface plasmon antenna

Report from Shizuoka University

Assist. Prof. Anitharaj Nagarajan and 7 bachelor students of Global Academy of Technology (GAT), Bengaluru, India have been invited to Research Institute of Electronics, Shizuoka University (SU), Hamamatsu, Japan from Aug. 3 to 9. This program was supported by Japan Science and Technology Agency Sakura Science Program (JST-SSP). I would like to report the activity of this program.

[1st day (Aug. 3)]

GAT members arrived at Chubu Centrair International Airport at 21:45, and I escorted to a hotel near the airport. It was impressive that they greeted me with smiles despite the long journey.

[2nd day (Aug. 4)]

In the morning, we took a direct bus from the airport to Hamamatsu Station. After arriving at Hamamatsu Station in the afternoon, we escorted them to their accommodation at SU, where we explained the details and the schedule of this program.

In the evening, we moved to an Indian restaurant near SU for a welcome party. Students from SU joined us and we introduced ourselves to each other. The Japanese students were a little shy and did their best to introduce themselves, but Japanese manga and anime seem to be well-known in India, and they had a lively talking of common topics.

[3rd day (Aug. 5)]

In the morning, we exchanged research ideas. Dr. Anitharaj from GAT received the Ph. D degree from SU in 2020 for her study on silicon photodetectors with surface plasmon antennas, and expressed interest in the recent progress at SU. GAT students also proposed new topics on this topic, which provided a fruitful opportunity for discussion.

In the afternoon, we visited Yamaha Innovation Road and viewed the many musical instruments developed by this company.

[4th day (Aug. 6)]

In the morning, the students measured the current in our fabricated devices. After the explanations of the operation principles of silicon photodetector with surface plasmon antenna, they actually operated the light irradiation system, prober, and semiconductor parameter analyzer.

In the afternoon, we entered the clean room, and the equipments for semiconductor device fabrication were introduced. Among them, they experienced the deposition of a gold film using the electron beam evaporation system.

Some GAT students had entered a clean room for the first time, and they were very interested.

[5th day (Aug. 7)]

In the morning, I explained the history of electromagnetic field analysis and how to solve Maxwell's equation using program codes.

In the afternoon, every student completed program code on their laptop and actually ran it. They analyzed how to propagate the electromagnetic wave from their results.

[6th day (Aug. 8)]

In the morning, we went to the Suzuki Plaza. We saw the products of vehicles and motorcycles. GAT and SU students danced together and took a video. I was surprised to see more friendly between GAT and SU students than on the 2nd day.

Around noon, we moved to Hamamatsu Station, where we enjoyed a lunch and shopping.

In the evening, we went to a Japanese restaurant for a farewell party. The GAT students expressed their hopes of studying at SU and their gratitude for the program, and SU also expressed its gratitude for the opportunity of this exchange.

[7th day (Aug. 9)]

Early in the morning, we took a direct bus from Hamamatsu Station to Chubu Centrair International Airport. After arriving, they had a few hours to spare before checking in for their flight, so they enjoyed shopping at the airport. We promised to meet again in future, and then GAT members went back to India.

■Summary

We would like to express our gratitude to this JST-SSP for their support and the wonderful opportunity to establish the strong collaboration between GAT and SU. We are hoping to strengthen exchanges of students/professors through the continued collaboration.
