Excitonic properties of ${\mathrm{Zn}}_{1\mathrm{-}\mathit{x}}$${\mathrm{Cd}}_{\mathit{x}}$Se/ZnSe strained quantum wells

We present a systematic investigation of the linear optical properties of ${\mathrm{Zn}}_{1\mathrm{-}\mathit{x}}$${\mathrm{Cd}}_{\mathit{x}}$Se/AnSe multiple quantum well structures in the excitonic region using absorption and photoluminescence measurements in the 10–300 K temperature range. Heavy- and light-hole excitonic transitions and heavy-hole exciton binding energies were measured for different well widths and compositions. A set of consistent parameters was determined within a two-band model, which accurately describes the excitonic properties of the strained ${\mathrm{Zn}}_{1\mathrm{-}\mathit{x}}$${\mathrm{Cd}}_{\mathit{x}}$Se quantum wells.
