Structural and optical properties of vertically aligned lnAs quantum dots (QDs) were embedded in Al0.5Ga0.5As spacer layers. The aligned QDs were grown at 520℃ in the Stranski-Krastanow (S-K) growth mode of molecular beam epitaxy. To improve QD characteristics, we employed a size- and density-contro...
