Abstract
We have investigated the band gap renormalization due to many-body effects in electron hole plasmas in quasi-two-dimensional multiple quantum well structures. A comparison of the data obtained in GaAs/GaAlAs-and GaSb/AlSb- structures show that the band gap shift - if scaled in effective Rydberg units - is independent of the material system. Theoretical calculations confirm this new universal relation governing the dependence of band renormalization on plasma density in two-dimensional systems.
