Va. Kaygorodov et al., Cd(Mg)Se single layers and CdSe/CdMgSe heterostructures grown by molecularbeam epitaxy on InAs(001) substrates, ACT PHY P A, 100(3), 2001, pp. 443-450
We report on molecular beam epitaxy of CdSe/CdMgSe heterostructures on InAs
(001) substrates and studies of their optical and structural properties. Th
e CdMgSe energy gap versus composition dependence is determined. The zinc-b
lende MgSe band-gap energy and optical bowing parameter are estimated to be
4.05 eV and 0.2 eV, respectively. The CdSe quantum wells embedded into CdM
gSe barriers demonstrate intense photoluminescence. Effective mass approxim
ation calculations of electron-heavy hole optical transitions in CdSe quant
um well are in a good agreement with the experimental data obtained.
