The current study uses various computational methods to determine the eigenvalues and eigenvectors of a specific system—namely, a two-impurity, two-electron system within a dumbbell-shaped quantum dot. Initially, the single-electron, single-impurit

The current work used the effective mass approximation conjoined with the finite element method to study the exciton states in a conical GaAs quantum dot. In particular, the dependence of the exciton energy on the geometrical parameters of a conical
