Abstract
The room-temperature electro-absorption in wide (similar to 150 Angstr om) ZnCdSe quantum wells is explained in terms of the quantum-confined Franz-Keldysh effect. The heavy hole-light hole splitting has been de termined both for single quantum well (SQW) and multiple quantum well heterostructures, providing an insight into the distribution of intrin sic strain. The band gap shrinkage due to the many-body Coulomb intera ctions is shown to be negligible in the SQW laser diode with the wide quantum well.
