We present a hybrid nanofabrication technology for realizing single-crystalline metal nanoparticle ensembles, such as trimers, heptamers and periodic arrays; well-suited for nanoplasmonics applications. Top-down engineered nanotemplates result in the deterministic formation of isolated polycrystalline gold islands with precise volume and position, which are transformed into single-crystalline nanoparticles using bottom-up self-assembly based on nanotemplate-guided thermal dewetting.

使用纳米模板引导的热去湿技术，用于金属纳米颗粒集合体的高精度纳米加工技术†

我们提出了一种混合纳米加工技术，用于实现单晶金属纳米粒子集成体，例如三聚体，七聚体和周期性阵列。非常适合纳米等离子体技术的应用。自上而下设计的纳米模板可确定性地形成具有精确体积和位置的孤立多晶金岛，然后使用基于纳米模板引导的热反润湿的自下而上的自组装将其转变为单晶纳米颗粒。
