In order to understand dislocations in GaN grown on silicon using metal organic chemical vapor deposition (MOCVD), two samples with different film thickness were grown. The distribution of dislocations and its influence on epitaxial layer were studied. Wet etching can effectively reveal the dislocations in GaN, [...]
