Outline of Final Research Achievements

Singularity structures including various lattice defects and nano-structures are systematically investigated from the computational materials science viewpoints. To this end, many computational methods are newly developed in addition to the ab initio-based approach incorporating growth conditions such as temperature and beam-equivalent pressure. Using these computational methods, singularity structure formation and its properties, such as surface reconstruction, dislocation, impurity, polarity, nanowire, quantum dot, and two-dimensional materials for compound semiconductors (mainly III-N compounds), are successfully clarified under the realistic growth conditions. On the basis of the results obtained in this study, crucial factors for the singularity structure formation are discussed to propose guiding principles for realizing them.

Academic Significance and Societal Importance of the Research Achievements

半導体は,情報・環境分野における次世代デバイス開発においても重要な役割を果たすことが期待されている。この半導体がデバイス(例えばトランジスタやLED)として機能するためには不完全性である欠陥の制御が不可欠である。本研究では、さまざまな欠陥を“特異構造”として統一的に位置づけ、特異構造を特徴づける“ヘテロボンド”に注目して、表面・界面を“場”として形成される“特異構造”に至る一連の過程を包括的に検討した。得られた成果に基づいて、現実の成長条件下での特異構造の創成指針さらには新奇物性発現の可能性を明らかした。
