Results for electron and hole confined in a GaAs-Al\(_{0.28}\)Ga\(_{0.72}\)As quantum dot-quantum ring: the sum of ground state energy levels of electron and hole (\(E_0^e+E_0^h\)) (a), the position expected value of the electron and hole along \(z-\)direction (b), the overlap integral according Eq. (6) (c), and the Coulomb energy obtained via the Eq. (5) (d). The solid spheres in (d) correspond to variational calculations with a two parameters trial wave function.
