The foundation gives an “academic incentive award” to those who have excellent and original research in natural science fields such as organic chemistry, inorganic chemistry, polymer chemistry, machine / measurement control / system, electricity / electronics, and medicine.

About awarded research
This study focuses on the control of electron carriers on surface plasmon resonances based on oxide semiconductor nanoparticles (NPs) in the near-infrared (IR) region. We developed active devices of transparent thermal-shielding techniques with plasmonic characteristics that can control optical properties selectively in visible and near-IR ranges. Particularly, we used oxide semiconductors to demonstrate electric control of surface plasmons based on dynamic carrier accumulations on the NP surfaces for electron doping into the NPs. The electron carriers injected into the NPs influence the carrier accumulations and electronic states in the NPs. These new techniques contributed to thermal management in terms of thermal shielding and their properties in the near-IR range.

Your impression & future plan

Surface plasmon studies on oxide semiconductors yielded important results, leading to social outcomes in the field of surface plasmons focusing on metal materials. Rather than riding a big tide, we would want to create mine, even if it is small. We strive for research that has a societal impact without being constrained by narrow academic fields or conventional wisdom.
