Description :
The effects of carrier density dependent mobility regime of low mobility insulator operating under steady state single injection space-charge-limited current flow with two sets of traps distributed in energy are investigated for the situation in which the concentration of lower energy trap distribution is larger than or equal to the one of the upper energy trap distribution. The regional approximation method is applied to obtain the simplified solutions for the complete current-voltage characteristic at different injection level of currents. It is shown that the couprate current-voltage characteristic is started from the pure Ohm’s law which finally merges into perfect trap-free space-charge-limited current flow for which the cube power law is valid. In the middle span of the characteristic, there are four current-voltage regimes which have complicated characteristic.
