Description

The aim of this work are (i) outline the basic ideas of the Effective-Mass Approximation (EMA), (ii) point out the major difficulties of the shallow-impurity problem, (iii) illustrate the similarities between the EMA treatment for shallow impurities and that for excitons, and (iv) provide a basic, introductory bibliography to the topic. (L.C.)
