aJ–E curves of CNTs doped at different Ag ion doses; b F–N plots of CNTs doped with different Ag ion doses. The J–E curves gradually shift to low applied fields and showed that the field emission characteristics
of the AD-CNT arrays were gradually improved as the Ag-doped dose increased from 0
to 3 × 1016 cm−2. Ag ion implantation with high doses makes the field electron emission performance
of the emitters worsen
