Abstract
The Lee-Low-Pines variational method is used to investigate the proper ties of a polaron in a quantum well (QW). The electron wave function i n a finite-height potential barrier has been used for the calculation. Therefore, the influence of the barrier height on the polaron propert ies is taken into account. GaAs/AlxGa1-xAs QW is chosen as an example to calculate the polaron energy and effective mass. Our results indica te that the barrier height has an important influence on the polaron p roperties in a QW.
