Abstract
The approximation made to quantum systems where a particle possesses an effective mass that depends on the position is relevant to many state-of-the-art compounds, which have been extremely useful in tailoring different quantum physical properties, specially in the field of semiconductors. The approach of a position-dependent mass has proved to be a very effective one in those cases where quantum wells emerge either in one or two dimensions. In the present work we discuss the interplay between m(x) versus the action potential V (x) in the Schrödinger equation, the presence of the one excluding the other. As an application, both approaches are compared in the benzene molecule.
