ZrFeSe
ZrFeSe is a semimetallic ternary iron-chalcogenide compound that exists in a metastable state with multiple structural variations.
About ZrFeSe
ZrFeSe is a complex ternary compound categorized within the iron-based materials class. Characterized by a near-zero-gap electronic structure, it functions as a semimetallic material that bridges the gap between metallic conductors and insulating phases, making it an intriguing subject for fundamental condensed matter research. Due to its position above the thermodynamic stability hull, this compound is considered metastable under ambient conditions. Its existence across multiple structural configurations highlights the structural flexibility inherent in iron-chalcogenide systems, providing researchers with a unique platform to investigate phase stability and electronic transitions.
Key Properties

How It Compares
Within the iron-based superconductors class.
Unlike the highly stable and widely utilized FeSe, which serves as a foundational superconductor in this class, ZrFeSe occupies a more precarious thermodynamic position. While siblings like FeSe2 and FeTe2 exhibit well-defined stoichiometric stability, ZrFeSe represents a more challenging synthetic target that requires careful control of growth conditions to access its diverse structural motifs.
