Understanding Doping, Vacancy, Lattice Stability, and Superconductivity in KxFe2− ySe2

چکیده
Metal-intercalated iron selenides are a class of superconductors that have received much attention but are less understood in comparison with their FeAs-based counterparts. Here, the controversial issues such as Fe vacancy, the real phase responsible for superconductivity, and lattice stability have been addressed based on first-principles calculations. New insights into the distinct features in terms of carrier doping have been revealed.

Floating-zone growth of KxFe2-ySe2 single crystals
The discovery of superconductivity at temperatures above 30 K in KxFe2-ySe2 compounds has attracted considerable attention [1]. The crystal structure of KxFe2-ySe2 descends from the well-known ThCr2Si2 structure with vacancies at the Fe sites. It was soon found that magnetism and superconductivity coexist in AxFe2-ySe2 (A = K, Rb, and Cs) [2-3]. Even in single crystals which show full shielding...
متن کاملInfluence of microstructure on superconductivity in KxFe2−ySe2 and evidence for a new parent phase K2Fe7Se8
The search for new superconducting materials has been spurred on by the discovery of iron-based superconductors whose structure and composition is qualitatively different from the cuprates. The study of one such material, KxFe2-ySe2 with a critical temperature of 32 K, is made more difficult by the fact that it separates into two phases-a dominant antiferromagnetic insulating phase K2Fe4Se5, an...

The discovery of superconductivity in LaFeAsO1−xFx has stimulated substantial interest in iron-based high-temperature superconductors (Fe-HTSs). Until now, several Fe-HTSs were discovered. They can be divided into two classes. The first class is iron pnictide materials.1−3 They contain two-dimensional FePn (Pn = pnictogens) tetrahedron layers and atomic sheets (e.g., Ba, K) or complex blocks [e...
متن کاملSpectromicroscopy of electronic phase separation in KxFe2−ySe2 superconductor
Structural phase separation in AxFe2-ySe2 system has been studied by different experimental techniques, however, it should be important to know how the electronic uniformity is influenced, on which length scale the electronic phases coexist, and what is their spatial distribution. Here, we have used novel scanning photoelectron microscopy (SPEM) to study the electronic phase separation in KxFe2...
متن کاملAnomalous correlation effects and unique phase diagram of electron-doped FeSe revealed by photoemission spectroscopy
FeSe layer-based superconductors exhibit exotic and distinctive properties. The undoped FeSe shows nematicity and superconductivity, while the heavily electron-doped KxFe2-ySe2 and single-layer FeSe/SrTiO3 possess high superconducting transition temperatures that pose theoretical challenges. However, a comprehensive study on the doping dependence of an FeSe layer-based superconductor is still l...
