Transient drift dominated bipolar conduction with recombination

A drift-dominated conduction model is often used in conduction analysis where the velocities of charge carriers are proportional to the local electric field through their mobilities, and in turn the electric field is related to the charge densities of the carriers through Gauss's law. Recent work for unipolar ion conduction has obtained generalized solutions for the transient time and spatial responses of the electric field and space charge distributions and for the terminal voltage-current characteristics for any initial and boundary conditions and for any type of terminal excitation or constraint.^1–3
