Abstract :
The finite-element technique based on a Galerkin method is applied to the eigenstate problem of semiconductor quantum wells with arbitrary potential profiles. In the present formulation, finite elements are employed only within the well region, and the contribution of the semi-infinite barrier region is evaluated analytically. Self-consistent solutions are obtainable by solving a matrix eigenvalue problem iteratively
