As4Cu4O16Tl8
As4Cu4O16Tl8 is a semiconducting quaternary cuprate oxide that is considered a promising candidate for experimental synthesis.
About As4Cu4O16Tl8
As4Cu4O16Tl8 is a complex quaternary oxide categorized within the cuprate superconductor class. Its electronic character is defined as semiconducting, distinguishing it from the metallic behavior often associated with high-temperature superconducting cuprates, and it occupies a near-hull position that suggests it is a viable target for experimental synthesis.
This material is of significant interest to researchers studying the structural diversity of copper-based oxides. With multiple reported structures, it serves as a valuable case study for understanding the coordination environments and chemical stability of thallium-bearing cuprates in solid-state chemistry.
Key Properties
