| dc.description.abstract | We have studied optical properties of V-shaped pits on Al0.16Ga0.84N. The microphotoluminescence spectrum from the pit center shows a broader and stronger emission at 350 nm than the near-band-edge emission at 336 nm from nonpit regions. The results indicated specific defect levels associated with the V-shaped pits. Furthermore, after using atomic force microscopy to probe the surface electrical potential with a conductive tip, the pit's potential was similar to0.2 V lower than its surrounding region. A simplified energy diagram is tentatively proposed to interpret our observation. (C) 2004 American Institute of Physics. | en_US |
