A NOVEL METHOD FOR SOLVING THE CONTINUITY EQUATIONS

This paper examines methods for the numerical solution of the continuity equations with the carrier concentrations as dependent variables. The emphasis is on the use of the preconditioned conjugate gradient method to solve the linear system arising from the discretisation of a continuity equation. This is achieved by a simple symmetrisation of the system matrix, which symmetrisation can be used for most discretisations arising from the Scharfetter‐Gummel method.
