Outline of Research at the Start

AlNやGaN、SiC、および、Ga2O3などの次世代半導体は、電力や光を極めて高効率に変換し輸送するトランスフォーマティブエレクトロニクスとして未来社会を支える根幹である。これらの材料には結晶欠陥が多数含まれ、実用化への弊害となりうる。本研究では、多光子励起過程を利用して次世代半導体の結晶欠陥を非破壊でイメージングする基礎技術を確立し、結晶欠陥密度を1桁以上低減させる手法を開発する。

Outline of Final Research Achievements

Observation, classification, and identifiation of crystal defects in widegap semiconductors were demonstrated using multiphoton excitation photoluminescence, and three-dimensional distribution of crystal defects was visualized. In GaN and SiC, dislocations can be visualized as dark lines due to the non-radiative recombination center nature of dislocations, and dislocation species can be identified and classified from shading and three-dimensional images. Furthermore, it was found that in SiC, through-plane dislocations and basal plane dislocations are observed as emission surfaces at wavelengths of around 400-500 nm for stacking faults. In Ga2O3, nanopipes can be visualized and correlated with surface hillock growth. In diamond, dislocations were observed as emission lines, revealing complex bending and propagation behavior during heteroepitaxial growth.

Academic Significance and Societal Importance of the Research Achievements

多光子励起フォトルミネッセンス法による結晶欠陥評価技術は、次世代半導体に複雑に分布する結晶欠陥の三次元分布を非破壊で可視化できる強力なツールとして、GaN、SiC、Ga2O3、ダイヤモンドと4種類の材料について適用できることを本研究課題を通じて示すことができた。これらの成果を基に結晶工学の発展と、次世代半導体を用いた光デバイスや電子デバイスの性能向上や信頼性向上に貢献しうるものと期待している。
