GaN nanorod light emitters attract increasing interest in the recent past due to their unique structural, optical and electronic properties. The main advantages inherent to nanorod systems are especially interesting for applications in solid state lighting. By recent progress in materials growth, good control on the fabrication of these 3D nanoLED structures could be obtained, even though open questions concerning growth mechanisms still exist.For small nanorod diameters the evanescent part of the electromagnetic mode outside of the nanorod will be able to efficiently interact with its immediate environment. The goal of this project is (in close collaboration with the partners) to establish the underlying technology to control both the GaN nanorod structures including their immediate environment, with the goal to study their interaction in detail and finally to implement new functionality.

GaN纳米棒发光体由于其独特的结构、光学和电学性质，近年来引起了人们越来越多的兴趣。纳米棒系统固有的主要优点对于固态照明中的应用特别有趣。随着材料生长技术的发展，尽管纳米棒的生长机制仍存在一些问题，但可以很好地控制三维纳米LED结构的制备。对于小直径的纳米棒，纳米棒外的电磁模式的倏逝波部分将能够有效地与其直接环境相互作用。该项目的目标是（与合作伙伴密切合作）建立控制GaN纳米棒结构（包括其直接环境）的基础技术，目标是详细研究它们的相互作用，并最终实现新功能。
