Three-dimensional visualization of lattice defects in -GaO via synchrotron-radiation Borrmann-effect X-ray topo-tomography
Yongzhao Yao, Daiki Katsube, Hirotaka Yamaguchi +4
beta-Ga2O3 is a promising material for next-generation power electronics; however, its performance is strongly affected by lattice defects such as dislocations. In this study, we d…

High-throughput, Non-Destructive, Three-Dimensional Imaging of GaN Threading Dislocations with in-Plane Burgers Vector Component via Phase-Contrast Microscopy
Yukari Ishiakwa, Ryo Hattori, Yongzhao Yao +2
We demonstrate a nondestructive, high-throughput method for observing dislocations in GaN (0001) using phase-contrast microscopy (PCM). The PCM images (359x300 m) analyzed…
