Due to their atomic-scale thickness, handling and processing of two-dimensional (2D) materials often require multistep techniques whose complexity hampers their large-scale integration in modern device applications. Here we demonstrate that the laser-induced forward transfer (LIFT) method can achieve the one-step, nondestructive printing of the prototypical 2D material MoS. By selecting the optimal LIFT experimental conditions, we were able to transfer arrays of MoS pixels from a metal donor substrate to a dielectric receiver substrate. A combination of various characterization techniques has confirmed that the transfer of intact MoS monolayers is not only feasible, but it can also happen without incurring significant defect damage during the process. The successful transfer of MoS shows the broad potential the LIFT technique has in the emerging field of printed electronics, including printed devices based on 2D materials.
由于二维（2D）材料具有原子级厚度，其处理和加工通常需要多步技术，而这些技术的复杂性阻碍了它们在现代器件应用中的大规模集成。在此，我们证明了激光诱导正向转移（LIFT）方法能够实现典型二维材料二硫化钼（MoS₂）的一步无损打印。通过选择最佳的LIFT实验条件，我们能够将MoS₂像素阵列从金属供体衬底转移到介电受体衬底。多种表征技术相结合证实，完整的MoS₂单分子层的转移不仅可行，而且在此过程中不会产生明显的缺陷损伤。MoS₂的成功转移表明LIFT技术在新兴的印刷电子领域具有广阔的潜力，包括基于二维材料的印刷器件。
