摘要

The V-shaped pit on Al-GaN by using the μ-PL and atomic force microscopy (AFM) was examined. The results showed that a specific defect-related band was introduced inside the V-pit region that gives rise to a dominant feature in μ-PL spectra. In addition, the V-pit-related levels were efficient relaxation channels for photoexcited carriers so that the new broader emission peak was enhanced significantly and the I _nbe was suppressed.
