Abstract

ZnO nanorod arrays grown by a simple non-catalytic polymer-template wet-chemical growth method were incorporated into blue InGaN-based LEDs to enhance the light extraction efficiency (LEE). Two types of ZnO nanorods, such as well-aligned ZnO nanorods (WAZNR) and not-well-aligned ZnO nanorods (NAZNR) were employed and compared with ITO-only electrodes. LEDs fabricated with WAZNR showed higher electroluminescence intensity and light output power than those with bare-ITO and NAZNR. The LED with WAZNR exhibited much higher EQE than those of the LEDs with bare-ITO and NAZNR. This result implies that the use of WAZNR can be an efficient processing tool for fabrication high performance GaN-based LEDs.
