Abstract

UNLABELLED

Ordered ZnO nanorod array/p-GaN heterojunction light-emitting diodes (LEDs) have been fabricated by introducing graphene as the current spreading layer, which exhibit improved electroluminescence performance by comparison to the LED using a conventional structure (indium-tin-oxide as the current spreading layer). In addition, by adjusting the diameter of ZnO nanorod array in use, the light emission of the ZnO nanorod array/p-GaN heterojunction LEDs was enhanced further. This work has great potential applications in solid-state lighting, high performance optoelectronic devices, and so on.

摘要

无标签

通过引入石墨烯作为电流扩展层制备了有序的氧化锌纳米棒阵列/p-氮化镓异质结发光二极管（LED），与使用传统结构（氧化铟锡作为电流扩展层）的LED相比，其电致发光性能得到了改善。此外，通过调整所用氧化锌纳米棒阵列的直径，氧化锌纳米棒阵列/p-氮化镓异质结LED的发光进一步增强。这项工作在固态照明、高性能光电器件等方面具有巨大的潜在应用。
