A silicon substrate patterned by an oxide is immersed in an alcohol solution of low-doped 1-nm Si nanoparticles. Reverse biasing draws particles to the substrate, mostly along the conducting current paths. Scanning electron and fluorescence microscopy show a tree-like network on the substrate. Avoidance of closed loops and preference for an angle of branching of 90 degrees-120 degrees are observed. The building block of the tree network is not individual particles but spherical particle aggregates approximately 150 nm in diameter.
一个由氧化物图案化的硅衬底被浸入低掺杂的1纳米硅纳米颗粒的醇溶液中。反向偏压将颗粒吸引到衬底上，主要沿着导电电流路径。扫描电子显微镜和荧光显微镜显示衬底上有一个树状网络。观察到避免形成闭环以及优先选择90度至120度的分支角度。树状网络的构建块不是单个颗粒，而是直径约150纳米的球形颗粒聚集体。
