我们提出了一种仅使用传统的微加工设施将硅纳米线（Si-NW）组装成几乎通用形状图案的方法。在该方法中，硅纳米线被胺基团官能化并分散在去离子水中。功能化的硅纳米线在悬浮液中表现出正表面电荷，并且它们被选择性地吸附并排列到固体基底上带负电荷的表面区域。作为概念证明，我们演示了基于单个 Si-NW 和长 Si-NW 网络的晶体管。
We present a method for assembling silicon nanowires (Si-NWs) in virtually general shape patterns using only conventional microfabrication facilities. In this method, silicon nanowires were functionalized with amine groups and dispersed in deionized water. The functionalized Si-NWs exhibited positive surface charges in the suspensions, and they were selectively adsorbed and aligned onto negatively charged surface regions on solid substrates. As a proof of concepts, we, demonstrated transistors based on individual Si-NWs and long networks of Si-NWs.
