Abstract

Nanowires (NWs) have potential to enable new types of light-emitting diodes (LEDs), which also entail challenges for the development of improved full device simulation models. In this work we calculate the extraction efficiency and emission enhancement in NW array LEDs at different temperatures and couple the results to carrier transport simulations. Our results show that the extraction efficiency of NW LEDs can be strongly temperature-dependent, which complicates the measurement of the internal quantum efficiency of NW LEDs. Through this work we demonstrate the need for full optoelectronic modeling tools in studying and developing new NW-based LEDs.
