Three‐Dimensionally Oriented Aggregation of a Few Hundred Nanoparticles into Monocrystalline Architectures

Abstract

Three-dimensional nanoarchitectures (see Figure) are formed by the oriented aggregation of CuO nanoparticles. One-dimensional orientation in the early stages of aggregation (in the [001] plane) of CuO nanoparticles is followed by formation of single-crystalline nanostructures consisting of hundreds of oriented nanoparticles.
