Abstract

The morphology and Cd distribution in CdSe/ZnSe quantum dot structures grown by molecular beam epitaxy is compared before and after the ZnSe cap layer deposition. Atomic force microscopy is applied to study the surface topography of uncapped samples without removing the samples from the ultra-high vacuum. The capped structures are analyzed by transmission electron microscopy. It is observed that only a highly specific growth procedure involving a thermal activation step leads to a Stranski-Krastanow morphology with three-dimensional CdSe islands on a thin wetting layer which are preserved after the overgrowth with ZnSe.
