PL spectra of pyramidal site-controlled QDs and fine-structure splitting measurement results. (Top) In0.25Ga0.75As nitrogen-free 0.5-nm nominal thickness QD PL and (top inset) fine-structure splitting of 19-μeV demonstration. (Bottom) In0.25Ga0.75As1−δ N δ PL spectrum (note the antibinding biexciton) and (bottom inset) a typical fine-structure splitting measurement result, showing no detectable values.
