• The stability of excitons confined in ZnSe/MgS Double Quantum Well (DQW) has been studied theoretically by tuning the confining well and barrier layer thickness using variation technique in effective mass approximation. Due to strong influence of phonons, the present calculations has involved exciton-longitudinal optical (LO) phonon interaction via Pollman and Buttner interaction potential. Strong localization of exciton has been evolved due to robust polaronic effects of individual carriers at its direct (DX) and indirect (IDX) form of confinements. Remarkably binding and inter-band transition energy values are observed to be larger for IDXs than for DX. The calculated interband transition energy values are in good agreement with the earlier results.
