Journal ArticleDOI
Efficiency droop in InGaN/GaN blue light-emitting diodes: Physical mechanisms and remedies
Giovanni Verzellesi,Davide Saguatti,Matteo Meneghini,Francesco Bertazzi,Michele Goano,Gaudenzio Meneghesso,Enrico Zanoni +6 more
TL;DR: In this article, the authors classified and reviewed the physical mechanisms causing the efficiency droop in InGaN/GaN blue light-emitting diodes and remedies proposed for droop mitigation.
Journal ArticleDOI
Theory of high field carrier transport and impact ionization in wurtzite GaN. Part I: A full band Monte Carlo model
TL;DR: In this paper, an ensemble Monte Carlo method was used to study high field electron and hole transport in wurtzite phase GaN using a nonpolar carrier-phonon interaction, which was treated within the framework of the rigid pseudoion approximation using ab initio techniques to determine the phonon dispersion relation.
Journal ArticleDOI
A numerical study of Auger recombination in bulk InGaN
TL;DR: In this paper, direct interband and intraband Auger recombination due to electron-electron-hole and hole-holeelectron transitions in bulk InGaN is investigated by first-order perturbation theory including Fermi statistics, realistic electronic structures obtained by nonlocal empirical pseudopotential calculations, and their corresponding wavevector-dependent dielectric functions.
Journal ArticleDOI
Physics-based modeling and experimental implications of trap-assisted tunneling in InGaN/GaN light-emitting diodes
M. Mandurrino,Giovanni Verzellesi,Michele Goano,Marco Vallone,Francesco Bertazzi,Giovanni Ghione,Matteo Meneghini,Gaudenzio Meneghesso,Enrico Zanoni +8 more
TL;DR: In this article, the effects of trap-assisted tunneling on the sub-threshold forward bias characteristics of a blue InGaN/GaN single-quantum-well LED test structure grown on a SiC substrate were investigated.
Journal ArticleDOI
Numerical analysis of indirect Auger transitions in InGaN
TL;DR: In this article, indirect phonon-assisted Auger recombination in bulk InGaN was investigated in the framework of perturbation theory, using first-principles phonon spectral density functions and electronic structures obtained by nonlocal empirical pseudopotential calculations.
