Figure 3
Synchrotron radiation X-ray diffraction data with Rietveld refinement for CZTS samples from mechanical alloying, thermally treated at 573 K (a) or 833 K (b) to stabilize the cubic or the tetragonal phase, respectively. Data are plotted as dotted blue, modelling as solid red and residual as dashed black. Models of individual phases are shown as coloured solid lines. Some of the most intense tetragonal superstructure reflections are marked by black arrows. |
