In the past two decades properties of various low dimensional heterostructures received much theoretical and experimental attention. The nature of the shallow (hydrogenic) states in such systems and their modification due to external magnetic field was widely investigated. Such effects are routinely studied with variational method within effective mass theory.
In this communication we focus on the influence of the smoothness of quantum well boundaries on donor states. Confining potential is taken in the form of Wood-Saxon potential. Such form of potential allows us to include the finite slope of the potential across quantum well boundaries. We also investigate the effects related to differences in effective masses and dielectric constants between well and barrier material and the influence of external magnetic field.
