FacileSynthesis of Metal Particle Decorated Vertical N-doped Carbon Nanotube/Graphene Hybrid films |
| 초록 |
The vertical N-doped carbon nanotube (VNCNT) arrays were decorated with Au, Ru and Mn nanoparticles and their effects on the field emission properties were investigated. The uniform catalyst nanoparticles were prepared by block copolymer lithography on graphene film, and the VNCNT arrays were grown from the nanopatterned catalyst particles by plasma-enhanced chemical vapor deposition (PECVD). Various metal particles were successfully decorated on the surface of VNCNT arrays. The field emission properties of the metal particle decorated VNCNT arrays followed the changes of the work function values, and the Mn-VNCNT firld emitter showed the best performance. This result revealed that the field emission of VNCNT arrays can be tuned by decorating metal particles, and the particle decoration with low work function material can be used for the development of efficient field emitters. |
