Description
A family of inorganic halide perovskites based on noble metals, synthesized using a 'stick & square' approach. The dataset, authored by Alaelddin Michailidis Barakat and last updated in April 2026, describes compounds with a general formula of A₄Au₂Pd□X₁₂ (A = Cs, Rb; X = Cl, Br, I). All compounds are black with sharp absorption edges in the near-infrared range and experimentally determined bandgaps between 0.8 and 1.55 eV.
Use Cases
Modeling bandgap properties for photovoltaic materials based on the described halide composition and vacancy ordering.
Analyzing crystal structure and symmetry based on the described pseudocubic unit cell and deltoidal icositetrahedral morphology.
Studying oxidation state validation and spectral response changes using the X-ray photoelectron spectroscopy (XPS) data referenced.
Benchmarking density functional theory (DFT) calculations against the experimental bandgap range of 0.8–1.55 eV.
Strengths
Includes experimentally determined bandgap values in the 0.8–1.55 eV range.
Describes a specific, synthesized family of compounds with the general formula A₄Au₂Pd□X₁₂.
Data is associated with peer-reviewed research methodologies, including XPS and DFT calculations.
Limitations
Dataset is very small at 7.1 KB, indicating limited scope.
Column-level documentation is absent; field semantics must be inferred after download.
