Abstracts

We present absorption measurements of a pseudomorphic Zn_{0.75}Cd_{0.25}Se/ZnSe superlattice and a Zn_{0.91}Cd_{0.09} Se/ZnSe single quantum well under high hydrostatic pressure applied by a diamond anvil cell. Excitonic transitions as 1s-heavy hole and 1s-light hole between the first bound states or minibands as well as transitions in the buffer material are visible. Transition energies are well understood by calculations of the band structure near Γ. The observed energy distance between photoluminescence and hh-absorption signal gives information on exciton localization. Whereas this distance is nearly pressure independent in the buffer, there is a significant increase at pressures P > 5 GPa for quantum structures.
