Igic, P. M.; Towers, M. S.; Mawby, P. A. Physically based 2D compact model for power bipolar devices. (English) Zbl 1074.35551 Int. J. Numer. Model. 17, No. 4, 397-405 (2004). The paper is devoted to the two-dimensional bipolar power devices. The reviewer is not an engineer and no technical aspects of the paper will be commented. Mathematically, the paper consists of solving the inhomogeneous diffusion equation with constant coefficients simultaneously in two different regions for different boundary conditions. The solution to the problem is searched for in special form. The discretization procedure leads to a system of coupled ordinary differential equations which in turn are solved by a difference method.
