ABSTRACTThe growth mode of CdSe layers grown by migration enhanced epitaxy between ZnSe barriers has been investigated. In situ reflection high-energy electron diffraction shows a gradual transition to a three-dimensional growth mode which, however, is not accompanied by a change of the surface lattice constant. High-resolution transmission electron micrographs reveal a strong Cd diffusion, leading to ternary ZnCdSe quantum wells. Furthermore. composition fluctuations perpendicular to the growth direction on a nanometer scale are found already prior to the beginning of the growth mode transition. In the case of heterostructures containing a CdSe layer that has undergone the growth mode transition, micrographs show Cd-rich quantum dots with diameters of around 8 nm and heights of around 1.5 nm within a ternary quantum well. By spatially resolved photoluminescence the emission from single quantum dots could be observed. The polarization dependence of the emission from single dots indicates an asymmetric shape of the dots with certain preferential orientations along the [110] and [110] directions.

Electromagnetically Levitated

By combination of electromagnetic levitation and copper-plate quenching, deep undercooling and non-equilibrium solidification of Si melts were realized. Several different morphologies of Si solidified at different undercoolings were found on the quenched surfaces, including spherical non-faceted morphology, faceted dendritic morphology, octahedral morphology and other polyhedral morphology. The mixed microstructures consisting of non-faceted and faceted morphologies in one single sample provide direct evidence for the growth mode transition from a continuous form to a lateral form.
