Journal ArticleDOI
Approaches for high internal quantum efficiency green InGaN light-emitting diodes with large overlap quantum wells
TL;DR: Optimization of internal quantum efficiency (IQE) for InGaN quantum wells (QWs) light-emitting diodes (LEDs) is investigated and the growths of linearly-shaped staggered In GaN QWs by employing graded growth temperature grading are presented.
Journal ArticleDOI
Polarization engineering via staggered InGaN quantum wells for radiative efficiency enhancement of light emitting diodes
TL;DR: In this article, a staggered InGaN quantum well with step-function-like In content in the quantum well offers significantly improved radiative recombination rate and optical gain in comparison to the conventional type-I In-GaN QW.
Journal ArticleDOI
Self-Consistent Analysis of Strain-Compensated InGaN–AlGaN Quantum Wells for Lasers and Light-Emitting Diodes
TL;DR: In this article, a strain-compensated InGaN-AlGaN quantum well (QW) structure consisting of thin tensile-strained AlGaN barriers surrounding the QW was investigated as improved active regions for lasers and light emitting diodes.
Journal ArticleDOI
Light Extraction Efficiency and Radiation Patterns of III-Nitride Light-Emitting Diodes With Colloidal Microlens Arrays With Various Aspect Ratios
TL;DR: In this article, fabrication studies of silica/polystyrene (PS) colloidal microlens arrays with various aspect ratios were performed on the III-nitride light-emitting diodes (LEDs).
Journal ArticleDOI
Current injection efficiency induced efficiency-droop in InGaN quantum well light-emitting diodes
TL;DR: In this paper, a self-consistent 6-band k ǫ p method is used to calculate the band structure for InGaN single quantum well (QW) based light-emitting diodes (LEDs).
