The paper presents a model of the space charge limited (SCL) electron conduction in a gap with a combination of free space and dielectric solid. The SCL electron current density J is solved numerically to obtain the voltage scaling of J ∼ VGn, and n is found to be between n = 3/2 (a vacuum gap) and...
