Direct observations of atomic structures of defects in GaN by high resolution Z-contrast stem

GaN/(0001)Sapphire grown by low pressure MOVPE is studied by high resolution Z-contrast imaging using STEM. First direct observation of the threading dislocation with edge character shows the atomic core structure, which appears to have a similar configuration to the {10-10} surface. The surfaces of...
