Structural analysis of graded Ag-In-Se/ZnSe core/shell nanocrystals. (a) Atomic reconstructions of Ag-In-Se/ZnSe core/shell nanocrystals, combining small- and wide-angle X-ray scattering results. The 5-shell ASAXS model is shown schematically on top of the reconstructions. (b) Radial Zn depth profile and (c,d) lattice mismatch calculations in [100] and [001] directions for the two Ag-In-Se/ZnSe core/shell nanocrystals. Data for thin ZnSe shell sample are shown in dark blue and for thick ZnSe shell sample in red. The lattice mismatch of an abrupt Ag-In-Se and ZnSe interface is illustrated in (c,d).
