Fig. 8From: Mechanochemical Solvent-Free Synthesis of Quaternary Semiconductor Cu-Fe-Sn-S NanocrystalsHRTEM images of the CFTS sample. The micrographs show the agglomerated nanocrystals (a, b) and isolated crystallites (c, d). The yellow squares display oriented crystallites, the corresponding FFT is depicted in the insets, and the zone axes and (h, k, l) of the corresponding phase are marked in yellow Back to article page
