This article introduces a novel transfer method for two-dimensional (2D) materials using functional tapes with adhesive forces tunable by ultraviolet (UV) light. The method is designed to efficiently and reliably transfer monolayer graphene and other 2D materials, such as bilayer graphene, transition metal dichalcogenides (TMDs), hexagonal boron nitride (hBN), and stacked heterostructures, onto various target substrates. The UV-tunable adhesive force allows for precise control over the transfer process, resulting in high-quality, defect-free 2D materials with a yield of over 99%. The method is solvent-free, flexible, and can be applied to a wide range of surfaces, including flexible polymers, paper, and three-dimensional objects. Additionally, the technique enables the creation of large-scale, patterned 2D material arrays, reducing material waste and production costs. The versatility and simplicity of the UV tape transfer method make it a promising tool for the development of electronic devices based on 2D materials.This article introduces a novel transfer method for two-dimensional (2D) materials using functional tapes with adhesive forces tunable by ultraviolet (UV) light.
