N2 - In this work, a template CVD method to produce graphene nanoribbons (GNRs) was developed with Cu nanoribbons as catalyst. Appropriate temperature, growth time and cooling rate were investigated and displayed the great importance for obtaining GNRs. The morphology, thickness and crystalline quality of the GNRs were characterized by the SEM, AFM, TEM (HRTEM and TEM diffraction), and Raman spectroscopy respectively, which indicated the GNRs had much narrower width, less layer numbers, smooth edges and higher crystalline compared to previous ones. Moreover, the electrical properties of the GNRs were measured and the mobilities reach 80e300 cm2 V1 s1. This research provides a new type of GNRs experimentally, which is of great importance for the graphene applications.
