Resumo
The donor binding energy of a hydrogenic donor impurity located in the center of a GaAs-AlxGa1-xAs circular quantum dot is
calculated by solving analytically the Schrödinger equation. The electron wave functions and the impurity energy levels are
determined in the standard manner through the solution of the transcendental equations obtained from the boundary conditions
imposed at the interfaces of the quantum disk. The roots of the transcendental equations were numerically found for quantum
disks with finite height of the confinement potential.
