The synthesis and integration of core-shell materials have been extensively explored in three-dimensional nanostructures, while they are hardly ever extended into the emerging two-dimensional (2D) research field. Herein, demonstrated by graphene (G) and hexagonal boron nitride (h-BN) and via a sequential chemical vapor deposition method, we succeed for the first time in synthesizing 2D h-BN-G core-shell arrays (CSA), which possess extremely high uniformity in shapes, sizes and distributions. Each of the core-shell units is composed of G ring-shaped shell internally filled with h-BN circular core. In addition, we perform simulations to further explain the self-symmetrical etching growth mechanism of the h-BN-G CSA, demonstrating its potential to be used as an efficient synthetic method suitable for other 2D CSA systems.

通过自对称蚀刻生长形成的六方氮化硼-石墨烯核壳阵列
核壳材料的合成和集成在三维纳米结构中得到了广泛的探索，而它们几乎没有扩展到新兴的二维 (2D) 研究领域。在此，通过石墨烯 (G) 和六方氮化硼 (h-BN) 证明，并通过顺序化学气相沉积方法，我们首次成功合成了二维 h-BN-G 核壳阵列 (CSA)，其具有在形状、尺寸和分布方面具有极高的均匀性。每个核壳单元由内部填充有 h-BN 圆形核的 G 环形壳组成。此外，我们进行了模拟以进一步解释 h-BN-G CSA 的自对称蚀刻生长机制，证明其作为适用于其他 2D CSA 系统的有效合成方法的潜力。
