25. (22 marks) The following question examines the perovskite crystal structure. a. Draw a unit cell of the perovskite crystal structure. Please clearly label all the atoms in the unit cell. (2 marks) b. Write the general chemical formula for a perovskite crystal. (1 mark) c. Derive the structure factor for a perovskite crystal. N Fhkl = \sum_{j=1} f_je^{2\pi i(hu_j+kv_j+lw_j)} where $f_j$ is the scattering intensity factor, which depends on the atomic number. (5 marks) d. Determine the value of $F_{hkl}$ for 4 scattering conditions. (8 marks) e. Sketch a XRD spectra, assuming the intensity of the diffraction peaks are proportional to the structure factor. Please label the locations on the x-axis of the first 6 diffraction peaks, assuming a wavelength of 1.8057 Å and a lattice constant of 3.998 Å. (6 marks)
