초록 | We report on the fabrication of the nano-generators based on ZnO nanorods and graphene hybrid nano-structures. The graphene/ZnO nanorod hybrid structure by mechanical exfoliation of the ZnO nanorod grown on graphite substrate. The Raman spectra of the exfoliated graphene/ZnO nanorod hybrid structure shows G and 2D band peaks that are shifted to lower wave numbers, indicating that the exfoliated graphene layer exists under a significant amount of strain. The I-V characteristics of the graphene/ZnO nanorod hybrid structure show current flow through the graphene layer, while no current flow is observed on the ZnO nanorod/polydimethylsiloxane (PDMS) composite without graphene, thereby indicating that the few-layer graphene was successfully transferred onto the hybrid structure. A piezoelectric nanogenerator is demonstrated by using the fabricated graphene/ZnO nanorod hybrid structure. The nanogenerator exhibits stable output voltage up to 3.04 V with alternating current output characteristics.
