论文摘要
降低的尺寸降低导致量子材料中的新现象，并且需要在降低的尺寸中加速材料发现纳米级量子材料。热机械纳米块是一种快速的合成方法，它会产生高质量的单晶量子纳米线，并在晶圆尺寸上具有受控尺寸。本文中，我们将纳米芯施加到摩托车的散装原料中的纳米线，这是一种三分点拓扑金属，具有极高的电导率，这对于低抗性互连非常有前途。令人惊讶的是，我们获得了单晶Mo $ $ _ {4} $ p $ _ {3} $纳米线，这是一个在室温下在大气压下的亚稳态阶段。因此，我们证明纳米芯可以产生其他纳米材料合成无法访问的亚稳态阶段，并且可以在高温和压力下探索以前无法访问的合成空间。此外，我们的结果表明，目前对纳米质量的界面固体扩散的理解是不完整的，这为探索固态扩散的机会是在封闭维度的高压和高温方案下的固态扩散。
Reduced dimensionality leads to emergent phenomena in quantum materials and there is a need for accelerated materials discovery of nanoscale quantum materials in reduced dimensions. Thermomechanical nanomolding is a rapid synthesis method that produces high quality single-crystalline quantum nanowires with controlled dimensions over wafer-scale sizes. Herein, we apply nanomolding to fabricate nanowires from bulk feedstock of MoP, a triple-point topological metal with extremely high conductivity that is promising for low-resistance interconnects. Surprisingly, we obtained single-crystalline Mo$_{4}$P$_{3}$ nanowires, a metastable phase at room temperature in atmospheric pressure. We thus demonstrate nanomolding can create metastable phases inaccessible by other nanomaterial syntheses and can explore a previously inaccessible synthesis space at high temperatures and pressures. Furthermore, our results suggest that the current understanding of interfacial solid diffusion for nanomolding is incomplete, providing opportunities to explore solid-state diffusion at high-pressure and high-temperature regimes in confined dimensions.
