The article "Transfer of 2D Films: From Imperfection to Perfection" by Phuong V. Pham et al. reviews the advancements in transfer techniques for 2D films, which are crucial for their integration into electronic and optoelectronic devices. The authors highlight the challenges associated with high-temperature synthesis methods and the need for efficient transfer techniques to ensure material quality and uniformity. They discuss various transfer methods, including wet, dry, and quasi-dry transfer, detailing their processes, mechanisms, and advantages and disadvantages. The review emphasizes the importance of minimizing surface damage and contamination during the transfer process. Key methods such as polymer-assisted transfer (using PMMA, PDMS, and paraffin), electrochemical-assisted transfer, dry transfer via polymer supporting layers (using PDMS and PPC), thermal release tape-assisted transfer, ultraviolet (UV) light-assisted transfer, metal-assisted dry transfer, and adhesive matrix-assisted transfer are thoroughly examined. The article also explores the use of inorganic membranes for transferring 2D films, particularly in forming van der Waals heterostructures. The authors conclude by discussing the feasibility of these transfer methods for practical applications and the potential for further research in this field.The article "Transfer of 2D Films: From Imperfection to Perfection" by Phuong V.
