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…

Three-dimensional visualization of threading dislocation in GaN by polarized-light microscopy
Yukari Ishikawa, Kisara Matsumoto, Kazuki Ohnishi +1
We demonstrate high-throughput three-dimensional imaging of threading dislocations in ammonothermal GaN wafers using polarized-light microscopy with collimated LED illumination. Th…
