Abstract

The optical properties of MgS/CdSe quantum structures grown by molecular beam epitaxy are characterized by photoluminescence (PL) spectroscopy. The increase in the CdSe thickness from 1 to beyond 3 monolayers results in the formation of, at first, quantum wells (QWs) and then quantum dots (QDs) by Stranski-Krastanov growth. The PL temperature dependence measurements show clear difference in the optical properties of QWs and QDs.
