Coulomb impurity in spherical quantum dot

We investigate hydrogen impurity in spherical quantum dot. We calculated wave functions and corresponding energies of electron/hole confined in quantum dot containing centered donor/acceptor impurity. Calculations were carried out for different dot size and different materials, such as ZnO and CdSe, with different electron and hole effective masses. Electronic structure obtained by means of calculation defines as emission spectra. The calculation results can also reveal whether space confinement can alter doping (n- or p-) abilities of materials.
