摘要

我们报告了一种生长后的方法来提高砷化镓纳米线的辐射复合效率，超出了使用表面钝化所实现的效率。这是通过将纳米线耦合到共振等离子体纳米腔来实现的，以减少少数载流子的辐射复合寿命，从而将辐射效率提高一个数量级。

Plasmonic cavities for increasing the radiative efficiency of GaAs nano wires

We report a post-growth approach to increase the radiative recombination efficiency of GaAs nanowires, beyond what has been achieved using surface passivation. This is done by coupling the nanowires to resonant plasmonic nanocavities to reduce the radiative recombination lifetime of minority carriers, thereby increasing the radiative efficiency by an order of magnitude.
