Non-Equilibrium Quantum Well Populations and Optical Characteristics of III-Nitride Lasers and Light-Emitting Diodes
Publié en 2011
COMSOL-based Ostendo’s Optoelectronic Device Modeling Software (ODMS) has been updated to include effects of non-equilibrium QW populations in semiconductor light-emitting and laser diodes.
III-nitride light emitters with different levels of polarity have been compared as an illustrative example of ODMS performance. Modeling proved that high intra-QW recombination rates in III-nitride light emitters make the QW populations strongly non-equilibrium and vulnerable to inhomogeneous injection in multiple-QW devices.
QW populations are further affected by disparate electron and hole transport across the active region.
