TL;DR: In this article, the InGaN multi-quantum-well (MQW) structure was used for laser diodes, which produced 215mW at a forward current of 2.3
Journal ArticleDOI
High-brightness InGaN blue, green and yellow light-emitting diodes with quantum well structures
TL;DR: In this paper, high-brightness blue, green and yellow light-emitting diodes (LEDs) with quantum well structures based on III-V nitrides were grown by metalorganic chemical vapor deposition on sapphire substrates.
Journal ArticleDOI
Superbright Green InGaN Single-Quantum-Well-Structure Light-Emitting Diodes
TL;DR: The luminous intensity of these green InGaN SQW LEDs (12 cd) was about 100 times higher than that of conventional green GaP LEDs (01 cd) as mentioned in this paper.
Journal ArticleDOI
InGaN Multi-Quantum-Well-Structure Laser Diodes with Cleaved Mirror Cavity Facets
Shuji Nakamura,Masayuki Senoh,Shin–ichi Nagahama,Naruhito Iwasa,Takao Yamada,Toshio Matsushita,Hiroyuki Kiyoku,Yasunobu Sugimoto +7 more
TL;DR: In this paper, the InGaN multi-quantum-well (MQW)-structure laser diodes (LDs) fabricated from III-V nitride materials were grown by metalorganic chemical vapor deposition on sapphire substrate with (11*BAR*2*bAR*0) orientation (A face).
Journal ArticleDOI
High-Power, Long-Lifetime InGaN/GaN/AlGaN-Based Laser Diodes Grown on Pure GaN Substrates
Shuji Nakamura,Masayuki Senoh,Shin–ichi Nagahama,Naruhito Iwasa,Takao Yamada,Toshio Matsushita,Hiroyuki Kiyoku,Yasunobu Sugimoto,Tokuya Kozaki,Hitoshi Umemoto,Masahiko Sano,Kazuyuki Chocho +11 more
TL;DR: In this paper, a GaN layer above the SiO2 mask area surrounding the window, corresponding to the lateral overgrowth, was nearly free of the threading dislocations and a high density was observed in the vicinity of GaN grown in the window regions.
