  • Abstract
    Summary form only given. Recently, we have revised the space charge limited (SCL) current in a cylindrical and spherical diode or Langmuir-Blodgett (LB) law [1]. A novel scaling law in semi-analytical form has been established [1]: Japp = 4/9 E0 √2eEc3/2/m√D [1+F(Re/Rα)] where Ec is the cathode electric field, D is the gap spacing and F is a correction factor depends on the radii of the cathode and anode. Note it is accurate over a wide range of parameters for planar, cylindrical and spherical diode.
