The article discusses the transfer of two-dimensional (2D) films and their van der Waals heterostructures, emphasizing the importance of efficient transfer methods for applications in electronics and optoelectronics. Current methods for synthesizing 2D films often involve high-temperature processes, which can lead to contamination and damage. To address these challenges, various transfer strategies have been developed, including wet, dry, and quasi-dry transfer methods. These methods aim to preserve the quality and uniformity of 2D films while minimizing surface damage. Wet transfer involves the use of a liquid medium, such as water or a chemical solution, to detach the 2D films from their growth substrates and transfer them to target substrates. Polymer-assisted transfer, using materials like PMMA, PDMS, and paraffin, is a common approach. PMMA is widely used due to its solubility in various solvents, but it can leave residues. PDMS is preferred for its flexibility and low toxicity, while paraffin provides a smooth surface and reduces wrinkles. PPC (polypropylene carbonate) is a recent advancement, offering a clean and efficient transfer method with minimal residue. Dry transfer methods, such as those using thermal release tape (TRT) or metal-assisted transfer, are also explored. TRT is effective for transferring materials without the need for solvents or high temperatures. Metal-assisted transfer, using materials like Ni, Au, or Pd, facilitates the exfoliation of 2D films from substrates. Adhesive matrix-assisted transfer uses polymer matrices to achieve precise alignment and transfer without sacrificial layers. Inorganic membrane-assisted transfer, using silicon nitride membranes, offers a clean and flexible alternative for transferring 2D heterostructures. The review highlights the importance of selecting appropriate transfer methods based on the specific requirements of the application, ensuring high-quality and uniform 2D films for device integration. The development of these transfer strategies is crucial for advancing the practical applications of 2D materials in various technological fields.The article discusses the transfer of two-dimensional (2D) films and their van der Waals heterostructures, emphasizing the importance of efficient transfer methods for applications in electronics and optoelectronics.
