Perovskite-Chalcogenide Epitaxial Heterostructures: Possibility of Multiple Axial Orientations of CsPbBr3 Nanocrystals on PbBi2S4 Nanorods

“…Moreover, for epitaxial junction, lattice matching remained another important parameter which needs appropriate facets having similar d -spacing and atomic arrangement for both materials at the interface. − All these factors indeed make the reaction system complex in solution, and hence, reports of epitaxial heterostructures on perovskite hosts are limited until date. Although a large number of heterosystems involving perovskites have been reported, most of them are composites or do not have any clear evidence or characterization of lattice interacting epitaxial junction and monodisperse heterosystems. − Hence, the study of facet chemistry for tuning the facets of halide perovskite hosts, selecting appropriate secondary materials, and configuring reaction parameters are important in establishing such nanocrystal heterostructures.…”
