A one-step anisotropic etching method is developed to specifically obtain armchair-edged graphene directly from graphite flakes on various substrates. The armchair edge structure of the produced graphene is verified by the atomic resolution images obtained from the fluid mode peakforce tapping AFM and the relatively high intensity of D band in the Raman spectra.
一种一步各向异性刻蚀方法被开发出来，以直接从各种基底上的石墨薄片中得到扶手椅型边缘的石墨烯。原子力显微镜的流体模式峰值力轻敲 AFM 获得的原子分辨率图像以及拉曼光谱中 D 带的相对高强度证实了所制备石墨烯的扶手椅边缘结构。
