论文摘要
石墨烯是一种碳原子的单层，被包装成二维晶体结构，由于其独特的结构和光学的电子特性，引起了人们的关注。化学蒸气沉积（CVD）的最新进展导致金属箔上高质量石墨烯的批处理产生。但是，需要进一步的应用程序，以这些石墨从其生长基板转移到目标底物的方式。在这里，我们报告了一种可升华的载体方法，该方法允许石墨烯高质量转移到任意基板上，包括半导体，金属和有机基质。由于无聚合物的过程，残留物和环境不友好的有机溶剂的内在问题已经解决。光学显微镜，扫描电子显微镜（SEM）和拉曼光谱证明了转移的石墨烯的高质量和清洁表面。这项工作提供了一种优化石墨烯转移并扩大石墨烯在大规模2D电子中的应用的新方法。
Graphene, a monolayer of carbon atoms packed into a two-dimensional crystal structure, attracted intense attention owing to its unique structure and optical, electronic properties. Recent advances in chemical vapor deposition (CVD) have led to the batch production of high quality graphene on metal foils. However, further applications are required in the way these graphenes are transferred from their growth substrates onto the target substrate. Here, we report a sublimable carrier method that allows the graphene to be transferred with high quality onto arbitrary substrates, including semiconductor, metal and organic substrates. The intrinsic problems of the residue and environmentally unfriendly organic solvents have been solved due to the polymer-free process. Optical microscopy, scanning electron microscopy (SEM) and Raman spectroscopy demonstrate the high quality and clean surface of the transferred graphene. This work provides a new way of optimizing graphene transfer and widens the applications of graphene in large-scale 2D electronics.
