异质材料的集成已经成为工程界面和电子结构的有力工具。2D材料的出现为新型异质结构提供了前所未有的机会，其形式为货车德瓦尔斯堆叠、横向缝合的2D层和更复杂的分层和3D架构。本书概述了生产这种货车范德华异质结构的最新方法，重点介绍了两种根本不同的策略，即自上而下的确定性组装和自下而上的合成。成功的技术，优点和局限性进行了讨论这两种方法。与制造本身同样重要的是对所产生的工程材料的表征，其中强调了一系列涵盖结构，成分和新兴功能的分析技术。人造货车德瓦耳斯结构的性质的实例包括光电子学和等离子体、双电子学和由从2D到3D晶体组分的货车德瓦耳斯组装的一般化产生的独特功能性。最后，目前的问题的可重复性，限制和机会，为未来的突破，在增强均匀性，界面纯度，功能控制和最终的数量级增加的复杂性的货车德瓦尔斯异质结构进行了讨论。
The integration of dissimilar materials into heterostructures has become a powerful tool for engineering interfaces and electronic structure. The advent of 2D materials has provided unprecedented opportunities for novel heterostructures in the form of van der Waals stacks, laterally stitched 2D layers and more complex layered and 3D architectures. This Primer provides an overview of state-of-the-art methodologies for producing such van der Waals heterostructures, focusing on the two fundamentally different strategies, top-down deterministic assembly and bottom-up synthesis. Successful techniques, advantages and limitations are discussed for both approaches. As important as the fabrication itself is the characterization of the resulting engineered materials, for which a range of analysis techniques covering structure, composition and emerging functionality are highlighted. Examples of the properties of artificial van der Waals structures include optoelectronics and plasmonics, twistronics and unique functionality arising from the generalization of van der Waals assembly from 2D to 3D crystalline components. Finally, current issues of reproducibility, limitations and opportunities for future breakthroughs in terms of enhanced homogeneity, interfacial purity, feature control and ultimately orders-of-magnitude increased complexity of van der Waals heterostructures are discussed.
