Analysis of the Three-Dimensional Model of Diffusion of Minority Charge Carriers Generated by an Electron Probe in a Heterogeneous Semiconductor Material by Means of Projection Methods

Algorithms for using the Galerkin projection method and the projection least squares method to analyze the three-dimensional model of the diffusion of minority charge carriers generated by an electron probe in a semiconductor material are presented. The results obtained using these methods are compared with the analytical solution. An estimate of the error is given, and the condition for the computation stability of the projection least squares method in the form of the limiting relation is obtained.
