ANALYTICAL PERTURBATION DERIVATION OF THE EXCITON BINDING-ENERGY IN GENERALIZED INFINITE QUANTUM-WELLS - APPLICATION TO TYPE-I AND TYPE-II FINITE-QUANTUM-WELL STRUCTURES

An analytical perturbation model for calculating the binding energy of excitons in generalized infinite quantum wells is presented. The posi tion and size of the wells for both particles can be different, allowi ng the consideration of many different geometries. Analytical derivati on has been developed to a point where the numerical final resolution is very much reduced. Since this is a perturbation method, the results can be as precise as one requires.
