It is found that the Langmuir-Blodgett solutions for the space charge limited current density, for both cylindrical and spherical diodes, may be approximated by Japp=(4/9)ε0√(2e/m)(Ec3/2/ √D) over a wide range of parameters, where Ec is the surface electric field on the cathode of the vacuum diode a...
