By using a modified Lee-Low-Pines variational method, we have investigated the groundstate binding energy of a polaron confined in asymmetric single and step quantum wells (QWs) due to interface phonons, confined bulk-like LO phonons, and half-space LO phonons. The relative importance of the differe
