Abstract

Nanoparticle polymer composites containing metal, semiconductor, magnetic, and optically active nanoparticles were deposited onto multiple substrates from a heatable atomic force microscope tip. The nanoparticle nanostructures were functional as deposited or could be etched with an oxygen plasma, revealing single nanoparticle lithographic resolution. Many types of nanoparticles can be patterned with the same technique, without the need to tailor the substrate chemistry and without solution processing.

摘要

含金属、半导体、磁性和光学活性纳米粒子的纳米颗粒聚合物复合材料从可加热原子力显微镜针尖沉积到多个基底上。纳米颗粒纳米结构具有沉积功能，也可以用氧等离子体进行刻蚀，从而实现单纳米颗粒光刻分辨率。许多类型的纳米颗粒可以用相同的技术进行图案化，而无需定制基底化学，也无需溶液处理。
