a JE curves of CNTs doped at different Ag ion doses; b F–N plots of CNTs doped with different Ag ion doses. The JE 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
