Characteristics of Field-Emission Emitters Based On Graphene Decorated ZnO Nanostructures

This paper investigated that the preparation of zinc oxide (ZnO) nanorod (NR) and ZnO NR with graphene material was successfully prepared and explored. The ZnO NRs without and with decorated graphene are also called ZO and ZO-G field-emission (FE) emitters. Besides, the material properties of fabric...
