Layer perovskites of the (CnH2n+1NH3)2MX4 and NH3(CH2)mNH3MX4 families with M = Cd, Cu, Fe, Mn OR Pd and X = Cl OR Br: Importance, solubilities and simple growth techniques
“…40 Transparent square platelet crystals were obtained by slow evaporation from solution. 55 The platelets are c oriented with edges typically along a = (a + b) and b = (a − b), where a and b are the orthorhombic axes in the plane.…”

“…Early in the 1970s, researchers had published papers about 2D perovskite materials in theoretical modelling [29][30][31][32][33][34] [35][36][37]. One of the two molecules must be sufficiently small to satisfy the tolerance limits, thus steadily existing in the gap of metal-halogen octahedron frame, named as small organic cation (A).…”

“…Crystals with dimensions up to 3 ϫ 3 mm 2 and thicknesses of 0.01-1 mm, were formed by slow evaporation of the solvent. 10 The structure and purity of the crystals were determined by single crystal and powder x-ray diffraction, on a Bruker APEX and D8 diffractometer, respectively.…”
Inorganic-organic hybrids are receiving increasing attention as they offer the opportunity to combine the robust properties of inorganic materials with the versatility of organic compounds. We have studied the electric properties of an inorganic-organic hybrid with the chemical formula: CuCl4(C6H5CH2CH2NH3)2. This material is a ferromagnetic insulator that can easily be processed from solution. We show that the surface conductivity of the hybrid can be increased by five orders of magnitude by covering the surface with an organic electron donor. This constitutes a novel method to dope perovskite-based materials and study their charge transport properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
