Large-scale, controlled fabrication of ordered phases is challenging at the nanoscale, yet highly demanded as their well-ordered structure and chemistry is the key for advanced functionality. Here, we demonstrate a general nanomolding process of ordered phases based on atomic diffusion. Resulting nanowires are single crystals and maintain their composition and structure throughout their length, which we explain by a self-ordering process originating from their narrow Gibbs free energy. The versatility, control, and precision of this thermomechanical nanomolding method of ordered phases provides new insights into single crystal growth and suggest itself as a technology to enable wide spread usage for nanoscale and quantum devices.

一般有序相的纳米成型。

大规模，有序相的受控制造在纳米规模上具有挑战性，但由于其有序排列的结构和化学性质是高级功能的关键，因此对它的要求很高。在这里，我们演示了基于原子扩散的有序相的一般纳米成型过程。产生的纳米线是单晶，并在其整个长度上保持其组成和结构，我们通过其窄吉布斯自由能产生的自排序过程对其进行解释。这种有序相的热机械纳米成型方法的多功能性，控制性和精度为单晶生长提供了新的见识，并提出了将其自身作为使纳米级和量子器件得到广泛应用的技术。
