A very thin layer of hexagonal boron nitride (h-BN) is an important 2D nanomaterial, sometimes called ‘white graphene’, with many properties distinct from graphene. However, the lack of controlled synthesis of high quality and wide-area films largely prevents realisation of the full potential of this material. In this review article, a comprehensive overview of the current status of the synthesis, growth mechanism using chemical vapour deposition, structure and electronic properties to tune the bandgap is covered. In particular, the progress towards achieving the improved quality and functionalities of the h-BN films via epitaxial growth and control of grain size, number of layers, morphology and orientation have been critically reviewed. In addition to synthesis and properties of the atomically thin (mono and few layer) h-BN, the applications in possible and emerging areas are also described and discussed.

具有可调整特性的层状六方氮化硼化学气相沉积法的进展及其应用

六方氮化硼（h-BN）的非常薄的层是重要的2D纳米材料，有时也称为“白色石墨烯”，其许多特性不同于石墨烯。然而，缺乏高质量和大面积薄膜的受控合成，很大程度上阻碍了这种材料的全部潜力的实现。在这篇综述文章中，将对合成的当前状态，使用化学气相沉积的生长机理，结构和电子性质来调节带隙进行全面概述。尤其是，已经对通过外延生长以及控制晶粒尺寸，层数，形态和取向来实现h-BN膜的改进的质量和功能性的进展进行了严格的综述。除了原子薄（单层和很少层）h-BN的合成和性质外，
