Figure 2
(a) Single isosurface of the phase and the best fit superimposed on a cut-away image of the crystal density. The point defect lines used to generate the fit (dots) and the direction of Q (arrow) are also illustrated. (b) Contour map of the cross section of the reconstructed phase of the complex density function on a plane passing through the middle of the nanocrystal. Smooth lines are the corresponding contours of the projection function Q·u(r), where u(r) is the strain field calculated for two rows of point defects (balls) of opposite sign. Both sets of contours have spacings of 0.24 rad. |
