| 英文摘要 | The spun carbon fibers were fabricated from multi-walled carbon nanotubes by a drawing and twisting method. The thermionic field emission behavior of the carbon fibers was investigated as a function of applied heating power P-H and field emission voltage V-F. The thermal field emission turn-on voltage and threshold voltage are found at electric field E = 2.6 V/mu m and E = 3.0 V/mu m, respectively. It is found that the emission current density, dominated by the field emission mechanism, reached up to J(0) = 1.3 A/cm(2) (P-H = 0 W) and J = 3 A/cm(2) (P-H = 2.0 W) at an emission field of E = 5.0 V/mu m. The lifetime with respect to heating power P-H, exhibiting about 45 h continuous luminescence under a constant P-H = 0.8 W, was investigated in the spun carbon fibers. Our results indicate that high-strength carbon fibers show good performance as a thermionic field emission source. |
