CdSe quantum dots grown on a Zn0.2Mg0.8S0.64Se0.36 barrier: MBE growth and μ-PL characterisation

We also discuss the possible mechanism behind the spectral diffusion seen in these measurements. Correlation of emission intensity from single-dot emission lines was also observed over much longer time periods (∼200 s). These results will be compared with previous results from CdSe dots grown on ZnSe barriers.
