Understanding doping, vacancy, lattice stability and superconductivity in KxFe2-ySe2
Yu Liu, Gang Wang, Tianping Ying +5
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, t…
Superconducting Phases in Potassium-Intercalated Iron Selenides
Tianping Ying, Xiaolong Chen, Gang Wang +6
The ubiquitous coexistence of majority insulating 245 phases and minority superconducting (SC) phases in AxFe2-ySe2 (A = K, Cs, Rb, Tl/Rb, Tl/K) formed by high-temperature routes m…
Quenching of superconductivity by Co doping in K0.8Fe2Se2
Tingting Zhou, Xiaolong Chen, Jiangang Guo +5
We synthesized a series of K0.8Fe2-xCoxSe2 samples with nominal compositions 0\leq x\leq 0.035 and investigated their physical properties. The results show that the superconductivi…
Superconductivity on the verge of Mott localization in ternary iron sulfide
Jiangang Guo, Xiaolong Chen, Gang Wang +5
We report the results of electrical and magnetic properties on two new compounds, K0.8Fe1.7S2 and K0.8Fe1.7SeS, both having similar structures to newly discovered superconducting K…
