Figure 7
Measured (open diamonds) and calculated (solid line) X-ray θ–2θ scan profiles of the (030) reflection from the 100 nm triclinic tin oxide nanobelt shown in Fig. 6. The calculation is based on the kinematic scattering theory, the lateral dimensions determined with SEM, and the single-lattice arrangement of atomic positions with a parameter of the number of atomic layers. The interference fringes and their frequency characterize the thickness of the nanobelt. The fitting of the profile led to a thickness of 29 nm. |
