摘要：

The growth of self-assembled CdTe quantum dots embedded in cubic MnTe by molecular beam epitaxy is reported. The dots are forced to form despite a small lattice mismatch of 2.3% between the dot and the barrier materials. Their properties are studied by means of time integrated and time resolved photoluminescence at various temperatures and magnetic fields. We demonstrate a considerable diffusion of Mn ions from the MnTe barrier into nominally nonmagnetic CdTe quantum dot, which is manifested as an enhancement of their magneto-optical effects, such as the Zeeman splitting of excitonic levels in the dots.
