Abstract
The photoluminescence linewidth of a CdTe/Cd1-xMnxTe structure, grown by molecular beam epitaxy, containing quantum wells of width 26, 37 and 45Å separated by large (250Å) barriers, was investigated. The high quality of the quantum well structure was confirmed by X-ray topography, X-ray rocking curves and narrow photoluminescence lines. It is shown that these results are consistent with small scale interface roughness resulting from clusters involving pairs or triplets of Mn2+ ions forming into small islands.
