石墨烯和其他二维货车德瓦尔斯材料的出现，以其独特的电学，光学和热学性质，为基础科学带来了巨大的进步。最近的发展表明，在维度上再向下迈出一步-从单层原子片到单个原子链-可以在基础科学和实际应用中带来令人兴奋的前景。原子链是材料缩小的终极极限，是建立一维量子材料全新领域的前沿。在这里，我们回顾了这个新兴领域的一维货车德瓦尔斯量子材料，并预测其未来的发展方向。我们专注于量子效应与电荷密度波凝聚，强关联现象，拓扑相位，和其他独特的物理特性，这是可以实现的具体在货车德瓦尔斯材料的低维。通过成分变化，空位和缺陷，以及它们在复合材料中的潜在应用工程准一维材料的性能的可能性进行了讨论。
The advent of graphene and other two-dimensional van der Waals materials, with their unique electrical, optical, and thermal properties has resulted in tremendous progress for fundamental science. Recent developments suggest that taking one more step down in dimensionality - from mono-layer atomic sheets to individual atomic chains - can bring exciting prospects in fundamental science and practical applications. The atomic chain is the ultimate limit in material downscaling, a frontier for establishing an entirely new field of one-dimensional quantum materials. Here, we review this emerging area of one-dimensional van der Waals quantum materials and anticipate its future directions. We focus on quantum effects associated with the charge-density-wave condensate, strongly correlated phenomena, topological phases, and other unique physical characteristics, which are attainable specifically in van der Waals materials of lower dimensionality. Possibilities for engineering the properties of quasi-one-dimensional materials via compositional changes, vacancies, and defects, as well as their potential applications in composites are also discussed.
