One-dimensional semiconductor nanowires are a promising candidate for future electronic devices. The epitaxial growth of nanowires is often mediated by metal seed particles, usually gold particles. In this paper the setup of a simple and robust technique to generate nanometer-sized aerosol gold particles by spark discharge is described. Furthermore we demonstrate for the first time that particles generated by spark discharge can be used to design advanced nanoelectronic structures, namely nanowires. In order to obtain compact, spherical particles suitable for nanowire growth, the sparkgenerated agglomerate particles were reshaped in a special compaction furnace. The reshaped particles were used to seed the growth of epitaxial GaP and InP nanowires, by metal organic vapor phase epitaxy, which was shown to be a reliable and reproducible method. This work indicates the possibility of using spark-discharge generated gold particles for the creation of new electronic devices even at large scale processing.

通过火花放电生成尺寸选择的金纳米粒子——用于外延纳米线的生长

一维半导体纳米线是未来电子设备的有希望的候选者。纳米线的外延生长通常由金属种子颗粒介导，通常是金颗粒。在本文中，描述了一种通过火花放电产生纳米级气溶胶金颗粒的简单而可靠的技术的设置。此外，我们首次证明火花放电产生的粒子可用于设计先进的纳米电子结构，即纳米线。为了获得适合纳米线生长的致密球形颗粒，火花产生的团聚颗粒在特殊的压制炉中重新成型。通过金属有机气相外延，使用重新成形的颗粒来种子外延 GaP 和 InP 纳米线的生长，这被证明是一种可靠且可重复的方法。
