Sphalerite-rock salt phase transition in ZnMnSe heterostructures
Abstract
We report on the investigation of epitaxial MnSe layers grown on ZnSe by transmission electron microscopy. MnSe/ZnSe superlattices (SLs) with different nominal MnSe thicknesses t{sub MnSe} between 2 and 20 monolayers (MLs) were investigated, which were grown by molecular-beam epitaxy on GaAs(001) substrates. Composition profiles of the SLs were evaluated by the measurement of local (002) lattice parameters in growth direction. A MnSe deposition between 2 and 4 MLs on ZnSe leads to the formation of intermixed Zn{sub 1-x}Mn{sub x}Se layers with sphalerite structure and a Mn concentration x increasing from 50% to 90%. For MnSe layers with a thickness between 6 and 20 ML, we observe 5-10 nm small MnSe inclusions with a rock salt structure embedded in sphalerite Zn{sub 1-x}Mn{sub x}Se with approximately 90%Mn.
