Quadruple Halide Perovskites: All-Inorganic
Noble-Metal Semiconductors wit
Alaelddin Michailidis Barakat published a dataset on figshare in April 2026 describing a unique family of inorganic halide perovskites. The dataset details compounds with the formula A₄Au₂Pd□X₁₂ (A = Cs, Rb; X = Cl, Br, I), which are black in color and have experimentally determined bandgaps in the 0.8–1.55 eV range. The data includes information on synthesis, crystal structure, and properties relevant for photovoltaic and infrared electronic applications.
