12. The FEM images were usually observed in field strength of a few hundreds V/cm (low field limit). The local field is expected to be amplified by the field enhancement factor due to the sharpness of the CNT tip. So, field emission typically occurs when the actual field at the tip is ∼0.5 V/Å in an experimental situation (see Ref. 11).
