本文以固体冠烯为碳源，采用常压化学气相沉积(CVD)方法在铜箔上成功制备了由单层和双层组成的大面积石墨烯薄膜。通过调节生长温度范围，实现了石墨烯层数的精确控制。此外，用拉曼光谱、透射电子显微镜和选区电子衍射分析了石墨烯的六方晶格结构。光学显微镜和扫描电子显微镜证实了石墨烯薄膜的连续性和均匀性。此外，室温下载流子迁移率为2120×cm2/vs的磁输运测量表明存在弱局域化。这种基于固体前驱体的常压CVD方法为制备石墨烯薄膜提供了一条简单、廉价和安全的途径。
In this paper, large-area graphene films composed of mono- and bi-layer have been successfully synthesized by atmospheric pressure chemical vapor deposition (CVD) on Cu foils using solid coronene as the carbon precursor. The number of graphene layers was precisely controlled by adjusting the growth temperature range. In addition, the hexagonal lattice of graphene was shown using Raman spectroscopy, transmission electron microscopy (TEM) and selected area electron diffraction (SAED). The continuity and uniformity of graphene films were confirmed by optical microscopy and scanning electron microscopy (SEM). Further, the presence of weak localization was shown by magneto-transport measurements with the carrier mobility of 2120 cm2/Vs at room temperature. This solid-precursor-based atmospheric pressure CVD method provides a simple, inexpensive and safe route for fabrication of graphene films.
