| 摘要: | Internal quantum efficiency (IQE) of InGaN-based ultraviolet light emitting diodes (LED) grown on patterned sapphire substrate (PSS) and flat sapphire were measured by photoluminescence and electroluminescence methods. The IQE improvement of PSS LED is significant. (C)2010 Optical Society of America |
