Figure 2
Perspective view SEM micrograph of an isolated 35 µm tall graded SiGe crystal which was used for the nanodiffraction experiment. The image also shows a schematic sketch of the scattering geometry with incident beam K0 and exit beam Ks defining the scattering vector Q. The yellow vectors define the reciprocal-space coordinates (Qx, Qy, Qz) and the blue arrows indicate the xy movements of the piezo stage. |
