The influence of the Pt cathode resistance on the field emission properties of field emitters fabricated using electron- or focused-ion beam induced deposition is investigated. In the case of the as deposited Pt field emitters, the slope of Fowler-Nordheim plot changes at a gate voltage of 55 V. On the other hand, the field emitters with annealing does not show the change in the slope of the FN plots. The I-V curve of the unannealed emitters could be fitted to the theoretical curve calculated from the FN theory by the compensation resistance of 1.6 MΩ. It indicates that this slope change is caused by the voltage drop due to the resistance of the field emitter itself.
