Swistacz, BA current flow problem for amorphous solids : A case of weak and mean electric fieldsA space charge transport problem for a planar capacitor system is presented. For a solid placed between two electrodes it is assumed that the carrier generation and recombination processes are independent of an external electric field. Some singular cases of the current flow trough the system are considered. It is found that the system can act as an almost perfect blocking diode (or a voltage stabiliser), and also, it is found that the negative differential resistance is a singularity of space charge transport through the system.solidnegative resistancespace chargetrapping levels20022002-09-23
