Description
Method of growth to get one single Mn in self-assembled semiconductors Quantum Dot (QD) is presented. A simple model proves that a very low Mn density is needed prior to the QD nucleation. This was reached by inserting a thin ZnTe spacer between a Zn1-xMnxTe buffer and the CdTe QD layer. Control of Mn ions density is made by changing the thickness of the ZnTe spacer, with good reproducibility. Qualitative and quantitative comparison of optical spectra for different samples assess this original method of growth
