Electroluminescent measurement of the internal quantum efficiency of light emitting diodes
Amorette Getty, Elison Matioli, Michael Iza, Claude Weisbuch, and James S. Speck
An experimental method is demonstrated for the determination of internal quantum efficiency (IQE) in III-nitride-based light-emitting diodes (LEDs). LED devices surrounded with an optically absorbing material have been fabricated to limit collected light to photons emitted directly from the quantum ... [Appl. Phys. Lett. 94, 181102 (2009)] published Tue May 5, 2009.
