Abstract
The polaron effect on the binding energy of a hydrogenic impurity and a Wannier exciton in a semiconductor quantum well is calculated by a variational approach. We have found that the correction due to the bulk-like LO-phonon effects is quite larger than that due to the continued LO-phonon effects and that these effects have a different behaviour.
