- Field electron emission;
In this work, pristine carbon nanotubes (CNTs) are grown in-situ with a variety of carbon allotropes (e.g., carbon nanoonions, nanocones, thin nanotubes, etc.) attached on the surface of the CNTs. The nanostructures of the hybrid carbon materials are characterized with transmission electron microscopy (TEM), and the structural dependence of field electron emission properties was investigated. It is found that the hybrid CNTs exhibit exotic morphologies having excellent field electron emission properties. These findings provide a simple synthesis method to assemble the carbon nanomaterials and a new insight into the fundamental understanding of high-performance CNTs towards applications in field-emission devices.
