(a) HRTEM image of a hematite crystal viewed perpendicular to the c axis. (b) Fast Fourier transform of (a). The marked spots have the observed d spacings 2.29 and 2.53 Å, corresponding to the 0006 and 1 $[\overline 1]$ 20 reflections of hematite, respectively. (c) Close up of the area marked with the white rectangle in (a). (d) Simulated HRTEM image of hematite.
