Solution epitaxial growth of formamidinium (FA) lead bromide on lead sulfide single crystals. a) Sketch of the lattices in cross-sectional and in-plane view. b–e) Scanning electron microscopic images of the ordered FAPbBr3 microcrystallites, obtained by drop casting of solu-tions with various precursor concentrations. f ) Histograms of the lateral dimensions of the micro-crystallites, deduced for four differently concentrated precursor solutions.
MagTop members, V. V. Volobuev, J. Korczak, T. Story, co-authored this work, where high-quality epitaxial growth of oriented microcrystallites on a semiconductor substrate was demonstrated for formamidinium lead bromide perovskite, by drop casting of precursor solutions in air.
