Journal ArticleDOI
III -nitride photonic-crystal light-emitting diodes with high extraction efficiency
TL;DR: In this article, a photonic-crystal structure for superior optical mode control was proposed for blue light-emitting diodes with a light extraction efficiency of 73% using InGaN-GaN devices.
Journal ArticleDOI
Carrier distribution in (0001)InGaN∕GaN multiple quantum well light-emitting diodes
Aurelien David,Michael Grundmann,John F. Kaeding,Nathan F. Gardner,Theodoros G. Mihopoulos,Michael R. Krames +5 more
TL;DR: In this paper, the carrier distribution in multi quantum well (multi-QW) InGaN light-emitting diodes was studied and it was shown that, no matter how many QWs are grown, only the QW nearest the p layer emits light under electrical pumping, which can limit the performances of high power devices.
Journal ArticleDOI
Droop in InGaN light-emitting diodes: A differential carrier lifetime analysis
Aurelien David,Michael Grundmann +1 more
TL;DR: In this article, the authors measured the differential carrier lifetime of an InGaN/GaN double-heterostructure light-emitting diode under varying electroluminescence injection conditions.
Journal ArticleDOI
Photonic-crystal GaN light-emitting diodes with tailored guided modes distribution
Aurelien David,Tetsuo Fujii,Rajat Sharma,Kelly McGroddy,Shuji Nakamura,Steven P. DenBaars,Evelyn Hu,Claude Weisbuch,Henri Benisty +8 more
TL;DR: In this article, epitaxial structures which modify the distribution of guided modes were introduced to enhance the potential for efficient light extraction by photonic crystal assisted gallium nitride light-emitting diodes.
Journal ArticleDOI

Christophe A. Hurni,Aurelien David,Michael J. Cich,Rafael I. Aldaz,Bryan Ellis,Kevin Huang,Anurag Tyagi,Remi Delille,Michael D. Craven,Frank M. Steranka,Michael R. Krames +10 more
TL;DR: In this paper, a flip-chip architecture for violet-emitting III-nitride (III-N) lightemitting diodes (LEDs) was proposed for high current density and high temperature.
