Figure 3
A coherent white-beam diffraction pattern featuring Au 111 Bragg peaks from a collection of nanoparticles with slightly different orientations. This image shows that the majority of Au particles scattering into the detector are oriented to diffract to the right-hand side, nearer to the surface-normal of the Si substrate. Using such a survey map, one can identify individual particles are both well separated in reciprocal space from other scattering particles and have a desired orientation with respect to the ensemble average particle orientation. |
