The recent interest to nanotechnology aims not only at device miniaturisation, but also at understanding the effects of quantised structure in materials of reduced dimensions, which exhibit different properties from their bulk counterparts. In particular, quantised metal nanowires made of silver, gold or copper have attracted much attention owing to their unique intrinsic and extrinsic length-dependent mechanical properties. Here we review the current state of art and developments in these nanowires from synthesis to mechanical properties, which make them leading contenders for next-generation nanoelectromechanical systems. We also present theories of interatomic interaction in metallic nanowires, as well as challenges in their synthesis and simulation.
最近对纳米技术的关注不仅旨在实现器件的小型化,还在于理解尺寸减小的材料中量子化结构的影响,这些材料表现出与它们的块状对应物不同的特性。特别是,由银、金或铜制成的量子化金属纳米线因其独特的内在和外在长度依赖性机械性能而备受关注。在这里,我们回顾了这些纳米线从合成到机械性能的当前技术水平和发展情况,这些特性使它们成为下一代纳米机电系统的主要竞争者。我们还介绍了金属纳米线中的原子间相互作用理论,以及它们在合成和模拟方面的挑战。
