Figure 4
Kinematical diffraction patterns simulated for perovskites with in-phase tilting about [001]. (a) The 〈100〉 ZADP obtained parallel to the tilt axis, (b) a 〈111〉 ZADP with the unique 〈110〉 axis indicated. Images (c) and (d) are simulations of the experimentally observed 〈100〉 and 〈111〉 zone-axis patterns, respectively, where multiple diffraction results in the appearance of additional reflections. |
