Self-Organized Formation of Compositionally Modulated ZnSe1−xTexSuperlattices

Synthesis of Cd-free water-soluble ZnSe1−xTex nanocrystals with high luminescence in the blue region

“…ZnSe 1−x Te x semiconductors are usually grown on a GaAs substrate by molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). Their structural properties, electrical properties, and lattice vibrations have been well studied [29][30][31]. However, colloidal ZnSe 1−x Te x NCs synthesized through either an organometallic or aqueous method have not been reported as far as we know.…”

Self-organized growth of alloy superlattices

“…The possibility of "natural" superlattices has been suggested previously, based on layered structures seen in epitaxial growth of alloys that are unstable against spinodal decomposition [5]. How-ever, only one instance of well-organized growth has been reported in such systems [6], and theoretical explanations remain speculative [7,8].…”

Coexistence properties of phase separation and CuPt-ordering in InGaAsP grown on GaAs substrates by organometallic vapor phase epitaxy

“…These temperature dependencies of the LCM and the VCM indicate that a correlation between two kinds of the phase separations exists. The VCM or self-organized natural superlattices in alloy layers such as ZnSeTe [31] and SiGe [32] have been observed; however, these studies are reported infrequently and the mechanism is poorly understood. Wang et al [33] have reported the formation of a VCM in an InGaAsSb epitaxial layer and found that the VCM was inclined by 41 with respect to the (0 0 1) terrace of the vicinal GaSb substrate.…”
