Abstract :
Conduction phenomena of charge carriers injected into insulating liquids from thin-film tunnel emitter have been studied on the basis of a charge injection model. In this model, pulsed charges are injected into a plane-to-plane gap when a step voltage is applied to the gap. It is shown that the current waveform obtained from this simulation is controlled by conduction current limited by the amounts of injected charges, although the waveform in low current densities has been explained by space charge freed current (SCFC) and in high current densities by space charge limited current (SCLC). A time at which a maximum value in the current waveform appears agrees with an experimental value only in the case that the: injected charges from the emitter is assumed to have a certain initial velocity
