title = "Ellipsoidal valley donor binding energies in a quantum well",
abstract = "We describe a modification of the usual separable wave function approach to donor electrons confined in heterostructures which reflects the intersubband Coulomb coupling. The donor Coulomb potential is split into effective normal and in-plane components which are then used to solve for the corresponding wave functions. The procedure is carried out self consistently which can be shown to result in the best donor wave function that can be expressed in separable form. As an example the method is applied to calculate a few of the lower lying levels of a donor in a quantum well in a material with a single ellipsoidal valley conduction band.",

note = "Funding Information: while allowing the donor Coulomb potential to be in-{"} cluded in the equation for the QW subbands. Since the wave functions are computed directly from differential equations as opposed to linear combinations found by variational methods, it is possible that they will give a better representation of the true donor state. As an application of the method, donor states in an AlAs QW were calculated and the effect of the donor position in the well on both the energies and wave functions demonstrated.
