| Outline of Final Research Achievements |
This research aimed to create "opto-iontronics," an extremely challenging optoelectronics with excellent material compatibility, based on carrier doping using electrolytes. Specifically, we worked on the following four areas and obtained results.
I. The effectiveness of electrolyte doping for various materials was elucidated by using transistor structures. Ⅱ Fabrication and evaluation of light-receiving and light-emitting devices by electrolyte doping. III. Fabrication of laser devices (LDs) using microfabrication technology and established the basic technology. iv. Solved difficulties and problems caused by the use of liquids in applications, as well as problems in device operation.

近年、Photo Detector（PD）・Light-Emitting Diode（LED）およびLaser Diode（LD）の用途は驚くほど多様化しつつある。具体的には、赤外光を用いた生体センシング・紫外光による殺菌や水質改善・単光子発生源を用いた次世代量子情報通信など、従来とは全く異なる光源が必要視されている。しかしながら、新しい発光材料を用いたPD・LED・LD開発には必ず大きな困難が伴う。そこで本研究は材料を選ばない受光・発光素子作製方法の確立に挑戦し、基盤技術を構築した。
