Abstract | The field emission properties of a single closed multiwalled carbon nanotube tip were investigated before and after doping with potassium. The threshold voltage was significantly reduced from 143 V to 76 V, but the emitter degraded in about 4 min. The current-voltage measurements fit the Fowler-Nordheim equation well up to about 100 nA of emission current. Additionally the work function of the multiwalled carbon nanotube tip could be estimated as being about 5.3 eV. |
