In this work we discuss the effective-mass approximation with a rapidly varying exterior potential and non-parabolic bands, recently proposed by Go´mez-Campos et al. In particular, we numerically test such an approximation confirming its validity on an explicitely solvable model.

Abstract
In this work we discuss the effective-mass approximation with a rapidly varying exterior potential and non-parabolic bands, recently proposed by Go´mez-Campos et al. In particular, we numerically test such an approximation confirming its validity on an explicitely solvable model.
