β-Ga2O3 is one of the most promising ultrawide band-gap semiconductor materials, but its crystal defects are not investigated comprehensively. The low angle grain boundaries of β-Ga2O3 crystal mainly exists in (100) plane. The existence of low angle boundary can destroy the integrity of the crystal structure and reduce the quality of crystal. The macroscopic analysis and microstructure characterization of the low angle grain boundaries in the β-Ga2O3 crystal grown by edge-defined film-fed growth method were carried out by chemical etching analysis and transmission electron microscopy. The results show that the shape and orientation of the etch pits on both sides of the low angle grain boundary are consistent, and the misorientation angle of the low angle grain boundary is 3°. In addition, the low angle grain boundary can cause the double peaks and broadening in the X-ray rocking curve. The gap in the study of low angle grain boundary is filled based on the characterization of the microstructure of low angle grain boundary in β-Ga2O3 crystals.

β-Ga2O3作为最具发展潜力的超宽禁带半导体材料,其晶体缺陷方面还缺乏深入且全面的研究。面缺陷小角晶界主要存在于β-Ga2O3(100)晶面,会破坏晶体结构完整性,降低晶体质量。采用化学刻蚀法和透射电子显微镜技术对导模法生长β-Ga2O3晶体中的小角晶界进行宏观分析和微观结构表征。研究表明:小角晶界两侧的刻蚀坑形状和朝向相同,晶界两侧的晶粒取向差约为3°,除此之外,小角晶界会使摇摆曲线出现肩峰及展宽,通过对β-Ga2O3晶体中小角晶界缺陷的微观结构进行表征,填补了小角晶界缺陷的研究空白。

β-Ga2O3作为最具发展潜力的超宽禁带半导体材料,其晶体缺陷方面还缺乏深入且全面的研究。面缺陷小角晶界主要存在于β-Ga2O3(100)晶面,会破坏晶体结构完整性,降低晶体质量。采用化学刻蚀法和透射电子显微镜技术对导模法生长β-Ga2O3晶体中的小角晶界进行宏观分析和微观结构表征。研究表明:小角晶界两侧的刻蚀坑形状和朝向相同,晶界两侧的晶粒取向差约为3°,除此之外,小角晶界会使摇摆曲线出现肩峰及展宽,通过对β-Ga2O3晶体中小角晶界缺陷的微观结构进行表征,填补了小角晶界缺陷的研究空白。

β-Ga2O3 is one of the most promising ultrawide band-gap semiconductor materials, but its crystal defects are not investigated comprehensively. The low angle grain boundaries of β-Ga2O3 crystal mainly exists in (100) plane. The existence of low angle boundary can destroy the integrity of the crystal structure and reduce the quality of crystal. The macroscopic analysis and microstructure characterization of the low angle grain boundaries in the β-Ga2O3 crystal grown by edge-defined film-fed growth method were carried out by chemical etching analysis and transmission electron microscopy. The results show that the shape and orientation of the etch pits on both sides of the low angle grain boundary are consistent, and the misorientation angle of the low angle grain boundary is 3°. In addition, the low angle grain boundary can cause the double peaks and broadening in the X-ray rocking curve. The gap in the study of low angle grain boundary is filled based on the characterization of the microstructure of low angle grain boundary in β-Ga2O3 crystals.
