Abstract

We use the Hanle effect to study spin relaxation in self-assembled CdSe quantum dots embedded in a Be0.03 Zn0.97 Se matrix. We measure a short transverse spin lifetime in the sub nanosecond range (0.31-0.35 ns) at 4.2 K. We propose that strong phonon and/or impurity scattering, due to unintentional contamination, limit the spin coherence time in CdSe / Be0.03 Zn0.97 Se QDs.
