This Feature Article gives insight into a buried stressor approach by which QD site-control is combined with self-alignment of current injection. An aperture within a laterally oxidized layer serves as buried stressor and simultaneously confines the current injection path of vertical pn-diodes. The figure shows a mesa and the buried stressor structure (inset). Exclusive QD nucleation at the mesa center is seen in the AFM image (upper image).
