The author considers the numerical solution of steady two-dimensional semiconductor equations. This is carried out by means of mixed finite element method on rectangles. The influence of quadrature is discussed, and Vanka-type relaxation is used, a comparison of the efficiency of pointwise and linewise methods being given. It is pointed out that for the use of a multigrid method, a hierarchy of grids is needed and estimates of truncation errors are given: a particular example is used and it is shown that the method gives satisfactory results.
