Luminescence of CdMnTe/CdMgTe structures with periodically arranged narrow-gap inclusions

Photoluminescence spectra of CdTe multi-quantum wells sandwiched by ultrathin MnTe layers and their temperature dependence

“…PL spectrum and its temperature dependence g CdMgTe = eV [8]), a broad PL band named 'B' coming from the CdMgTe layers appears at ∼2.4 eV [9]. Below the B band, four PL bands are clearly observed and they can be assigned to the PL band of the respective CdTe QWs with the thicknesses of 4, 8, 16 and 32 MLs from higher to lower energy sides.…”
