We will report on a systematic analysis of above aspects carried out by means of numerical device simulations. The aims of this analysis are (i) to improve understanding of droop mechanisms, (ii) to provide guidelines for LED optimization. Specific results will address 1) the suitability of pure droop mechanisms and/or the combination of 2 or more mechanisms to explain the droop, 2) the effects of above technological changes on IQE vs current curves

Abstract
We will report on a systematic analysis of above aspects carried out by means of numerical device simulations. The aims of this analysis are (i) to improve understanding of droop mechanisms, (ii) to provide guidelines for LED optimization. Specific results will address 1) the suitability of pure droop mechanisms and/or the combination of 2 or more mechanisms to explain the droop, 2) the effects of above technological changes on IQE vs current curvesFile in questo prodotto:
