摘要
A hybrid 1D/3D approach to modeling of the electric current spreading in a light emitting diode (LED) die is suggested and validated by comparing the theoretical predictions with available observations. Large-area LEDs with different contact electrode configurations suitable for high-power operation are analyzed in terms of simulations with the focus on the current non-uniformity and its impact on the device electrical and optical characteristics. The factors controlling the LED series resistance are identified by modeling, and ways for the resistance improvement are examined. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
