5. The picture below represents an electron diffraction pattern LazZnO₂Se₂ looking down the c-axis. The researcher who made the material initially recorded an X-ray diffraction pattern and tried to index it using a tetragonal unit cell. This wasn t successful. Looking at the pattern below, can you suggest why? 2 1/hm 5. The picture below represents an electron diffraction pattern LazZnO₂Se₂ looking down the c-axis.
