Title: Group iii nitride-based semiconductor light-emitting device and epitaxial wafer
Inventor: SHIOYA YOHEI
IPC: H01L33/32
Filed: 2008-07-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a group III nitride-based semiconductor light-emitting device which improves quantum efficiency by reducing overflow of positive holes from an active layer.  <P>SOLUTION: An active layer 19 is positioned between a p-type GaN semiconductor region 15 and a positive hole block layer 17, and positive holes H are supplied to the active layer 19 from the p-type GaN semiconductor region 15. The thickness D17 of the positive hole block layer 17 is less than thickness D13 of a GaN semiconductor layer 13. Since a band gap G17 of the positive hole block layer 17 is larger than the maximum value of the band gap of a GaN semiconductor region 23, the positive hole block layer 17 acts as a barrier wall ΔG<SB>H</SB>against positive holes which overflow the active layer 19. Thus, the positive hole block layer 17 reduces the amount of positive holes that overflow the active layer 19 to reach the GaN semiconductor region 23.  <P>COPYRIGHT: (C)2010,JPO&INPIT
