There have been breakthroughs in the mass production of graphene by chemical vapor deposition (CVD) and its practical applications have also been identified. Grain boundaries are typically present in ‘CVD graphene’ and adversely impact its properties. We summarize recent progress in growing large-area single-crystal graphene. Centimeter-scale single-crystal, truly single-layer graphene (SLG) films have been reportedly achieved on single-crystal Cu(111) foils by CVD growth, while meter-scale single-crystal SLG films have been reportedly produced with assistance of a roll-to-roll technique. The growth of uniform single crystals of bilayer or multilayer graphene over a large area remains an exciting challenge. Layer-by-layer transfer and the stacking of single-crystal SLG is considered a promising route to making new types of ‘single’ crystals or quasicrystals with specific numbers of layers and different stacking angles.

大面积单晶石墨烯的合成

通过化学气相沉积(CVD)大规模生产石墨烯已取得突破,其实际应用也得到了确认。晶界通常存在于“ CVD石墨烯”中,并对其性能产生不利影响。我们总结了在生长大面积单晶石墨烯方面的最新进展。据报道,通过CVD生长在单晶Cu(111)箔上获得了厘米级的单晶,真正的单层石墨烯(SLG)膜,而据报道,在单晶Cu(111)的帮助下生产了米级的单晶SLG膜。卷对卷技术。双层或多层石墨烯的均匀单晶在大面积上的生长仍然是一个令人兴奋的挑战。
