The space charge limited current is several times lower than the current calculated with the Fowler-Nordheim formula. The image-charge is taken into account with a spherical approximation, which is good around the top of the tip, i.e. region where the current is generated.1-6eninfo:eu-repo/semantics/openAccessPhysicsPlasma PhysicsEðlisfræðiinfo:eu-repo/semantics/articleArXiv e-prints:1608.06789
