Abstract: The electrical behaviour of an insulator has been studied for a single injection (electrons) current flow containing significant density of thermally generated free carriers under density dependent mobility mode. The current injection in CDDM mode with spherical geometry has been further studied. In this problem, it is found that at low current injection, the pure Ohm’s law for current-voltage characteristics has finally been converted into the half power law at high injection level under space charge regime.
