Outline of Final Research Achievements |
We have experimentally demonstrated SiC-dots with 1 to several-nm size in both Si and SiO2 fabricated by hot-ion implantation and the post N2 annealing processes. SiC-dots can emit very large photoluminescence (PL) from near-UV to near-IR ranges. Especially, SiC quantum dots (QDs) in SiO2 layer realize the PL emission coefficient enhancement caused by the strong confinement of excited electrons in QDs. Thus, SiC-dots become very promising structures for a future Si-based photonic device.

Academic Significance and Societal Importance of the Research Achievements |
ULSI製法と互換性のある簡易なホットイオン注入を一般的なSi基板及びSiO2層に行うだけで,低次元(0次元)SiCの形成と,その大きな発光特性が実現できた.本研究のSiCドット構造は,量子効果実現の学問的意義のみならず,安価な新規Si系発光デバイス応用,及びULSI用電子素子とのハイブリット素子としても将来有望であることが判明した.
