20. A minority of segments are Ag-rich with little or no S, probably due to the decomposition of Ag-S compounds by the electron beam (38). This beam damage also distorted the phase and prevented accurate images from being acquired with high-resolution TEM.
21. For these experiments, TEM images show that the original CdS rods were 5.3 by 50 nm, and the striped rods made from these had 5.3-by-11-nm CdS grains.

26. 2S (cubic and monoclinic), the anion sublattice assumes a body-centered-cubic structure with only slight distortions in the monoclinic phase (59). Several epitaxial relationships were considered, and the epitaxial connection with minimal lattice distortion to the (001) CdS face is the body-centered-cubic (110) face [monoclinic (100) face].

28. When the segments are very close to each other, however, the elastic energy is actually lowered. With only three atomic layers separating the segments (leftmost point in Fig. 4B), the number of distorted layers in the z direction is small, which results in a smaller repulsive interaction. Additionally, the interaction of the radial distortions from the two segments is cooperative (unlike the z-direction distortions), because they pull the atoms in the same direction. The overall result is a lowering of the elastic energy.
