A desirable feature is the ability to scale the extraction efficiency for large chips in order to reduce costs. In almost all cases, the use of large surface LEDs is detrimental due to the long ray paths to reach the sidewalls except for those extraction scheme

Yun Zhou,Tao Xu,Yanping Cai,Xiaojun Wu,Bei Dongth planes, these fields can be significantly reduced or even eliminated. In addition, due to the reduction of in-plane symmetry, a number of new heterostructure design options emerge to control the optoelectronic properties of non- and semipolar light emitters. Among these are the occurrence of anis

We also calculate the sensitivity of the model to the LED parameters and surface roughness. Finally, we apply this technique to calculate the IQE of both a state-of-the-art and a low pe
