title = "Cylindrical symmetry and spurious solutions in eight band k·p theory",
abstract = "Spurious solutions in eight band k·p theory for low-dimensional semiconductor heterostructures is a well-known problem. In this paper we study two approaches for the removal of spurious solutions, the plane wave cutoff approach [1] and the approach suggested by Foreman [2] where the Kane parameter is changed. We show that in order to use the plane wave cutoff approach for a cylindrical symmetric system Bessel functions has to be used as the expansion basis in the radial direction. Furthermore we compare the two approaches for a InAs/GaAs conical quantum dot.",
