FIG. 1.

(Color online) Powder-diffraction pattern of thioglycerol-stabilized nanoparticles and calculated patterns for (a) zinc-blende and wurtzite-structural models and (b) zinc-blende models for three different sizes. Atomic models and their layer stacking sequences for zinc blende and for wurtzite, respectively) are also shown.

FIG. 2.

(Color online) Powder-diffraction pattern of thioglycerol-stabilized nanoparticles and calculated patterns for zinc-blende and wurtzite-structural models. The best agreement between measured and calculated data can be obtained using a model with a distorted wurtzite unit cell.

Image of FIG. 3.
FIG. 3.

(Color online) Powder-diffraction pattern of glutathion-stabilized nanoparticles and calculated patterns for pure wurtzite- and zinc-blende structural models of spherical particles (red dotted and blue dashed lines, respectively) as well as two models including stacking faults. The latter models consist of equal volume fractions of zinc-blende and wurtzite structure and have a layer-stacking sequence of . One represents a spherical particle with a diameter of (solid black line), the other one a cylindrical particle (diameter of and height of , magenta dash-dotted line) which is shown in the inset. In all cases a lattice distortion of in and in was included.
