Determination of Burgers-vector directions of threading edge dislocations in GaN by phase-contrast microscopy
Yukari Ishikawa, Maki Shimizu, Koji Sato +4
Phase-contrast microscopy enables rapid, nondestructive observation of threading dislocations in GaN, but the relationship between dislocation contrast and the Burgers vector has n…

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 i…
