多年来，二维(2D)材料因其优异而独特的性能而取得了重大进展。在各种2D材料的制备方法中，化学气相沉积(CVD)被认为是实现大面积、高质量2D薄膜生长的最有前途的方法。此外，为了实现2D材料在不同领域的潜在应用，将2D材料集成到功能器件中是必不可少的。然而，普通化学气相沉积制备的材料在衬底上是随机分布的，不利于器件阵列的制作。为了解决这一问题，开发了一种现场选择生长方法，以满足实际应用的批量生产要求，因为它实现了对产品位置的控制，并有利于后续的直接集成。本文综述了近几年来位选择性合成的方法，包括籽晶法和图案化生长法。然后，对所生长的2D材料在电子学和光电子学方面的应用进行了综述。最后，讨论了选址方法和应用方面存在的挑战和未来的展望。
Over the years, there have been major advances in two-dimensional (2D) materials on account of their excellent and unique properties. Among the various strategies for 2D material fabrication, chemical vapor deposition (CVD) is considered as the most promising method to achieve large-area and high-quality 2D film growth. Furthermore, to realize the potential applications of 2D materials in different fields, the integration of 2D materials into functional devices is essential. However, the materials made by common CVD are randomly distributed on substrates, which is disadvantageous for fabricating arrays of devices. To solve this problem, a site-selective growth method was developed to meet the requirement of batch production for practical applications because it achieves control over the locations of products and benefits the subsequent direct integration. Herein, state-of-the-art methods for site-selective synthesis, including seeded growth and patterned growth, are reviewed. Then, the electronic and optoelectronic applications of the as-grown 2D materials are also reviewed. Finally, the remaining challenges and future prospects regarding site-selective methods and applications are discussed.
