Electron, Phonon, and Superconducting Properties of Yttrium and Sulfur Hydrides under High Pressures

We have analyzed the electron, phonon, and superconducting properties of binary hydrides YH₆, H₃S, YH₁₀, UH₁₀, and CaH₁₀, as compared to the properties of ternary hydride YS₄H₄ using a unified physical and computational approach to determining the stability range and the superconducting transition temperature. The normal and superconducting characteristics of ternary hydride YS₄H₄ at high pressure are calculated. The results for ternary hydride YS₄H₄ are compared with the properties of YH₆, H₃S, YH₁₀, UH₁₀, and CaH₁₀ compounds.
