Energy levels of two-dimensional polaronic donor

Abstract EN

Using a vibrational approach, the ground and the first two excited states of a two-dimensional platonic donor are studied over the entire range of the coupling constants.

It is observed that the platonic effects become more pronounced for strong Coulomb fields.

The degeneracy between the two excited states (the 2s and the 2p) is found to be lifted at lower values of the platonic coupling constant as the Coulomb strength increases.
