Abstract
AbstractWe present a detailed study of the influence of growth parameters on the broadening of CdTe-CdMnTe interfaces using a new magneto-optical technique [1,2] in MBE-grown quantum wells and superlattices. For growth temperatures up to about 300°C the Mn content decreases exponentially at the CdTe on CdMnTe interface and conversely the Cd one decreases exponentially at the CdMnTe on CdTe interface. At temperatures exceeding 300°C an additional broadening takes place which acts equally on both interfaces. Growth interruptions and modified flux stoechiometry do not exhibit significant influence on the broadening.
