Graphene and other two-dimensional (2D) materials can be used to create electronic and optoelectronic devices. However, their development has been limited by the lack of effective large-area transfer processes. Here we report a transfer method that uses functional tapes with adhesive forces controlled by ultraviolet light. The adhesion of the tape is optimized for the transfer of monolayer graphene, providing a yield of over 99%. Once detached from the growth substrate, the graphene/tape stack enables easy transfer of graphene to the desired target substrate. The method can be used to transfer other 2D materials, including bilayer graphene, transition metal dichalcogenides, hexagonal boron nitride and stacked heterostructures. The solvent-free nature of the final release step facilitates transfer to various target substrates including flexible polymers, paper and three-dimensional surfaces. The tape/2D material stacks can also be cut into desired sizes and shapes, allowing site-selective device fabrication with reduced loss of 2D materials.

石墨烯和其他二维 (2D) 材料可用于制造电子和光电设备。然而，由于缺乏有效的大面积转移工艺，它们的发展受到限制。在这里，我们报告了一种使用功能性胶带的转移方法，其粘合力由紫外线控制。胶带的粘合力针对单层石墨烯的转移进行了优化，产量超过 99%。一旦与生长基底分离，石墨烯/带堆叠就可以将石墨烯轻松转移到所需的目标基底。该方法可用于转移其他二维材料，包括双层石墨烯、过渡金属二硫属化物、六方氮化硼和堆叠异质结构。最终释放步骤的无溶剂性质有利于转移到各种目标基材，包括柔性聚合物、纸张和三维表面。胶带/2D材料堆叠还可以被切割成所需的尺寸和形状，从而允许选择性设备制造，同时减少2D材料的损失。
