Abstract
ABSTRACT Pressure-associated phonon-induced opto-electronic properties are brought out in a CdS/CdSe/CdS double quantum well. The effects of pressure on the interband associated with the changes of refractive index and optical absorption coefficients are investigated in the asymmetric well by altering its right well size and the barrier size. Aldrich and Bajaj polaronic effect is employed in the Hamiltonian. The effects of pressure on the optical properties due to the interband transition in the double quantum well are carried out. The single band effective mass, envelope function approximation and density matrix are used as theoretical tools in order to obtain these properties. The pressure produces a reduction in a radiative life time. The enhancement in the magnitude of absorption coefficients occurs due to the applications of hydrostatic pressure. The results bring out the fact that the optical susceptibilities suffer a blue shift and its magnitudes are determined by the matrix elements.
