High-Temperature Superconductivity in Li₂YH₆ Driven by Li Doping and a Specific Hydrogen-Cage Structure under High Pressures
Key Points
To explore the superconducting properties of Li₂YH₆ and its stability under high pressure.
Computed the likely phase of Li₂YH₆ using theoretical models under pressures of 130–180 GPa.
Evaluated its structural stability and superconducting characteristics in the I4/mmm phase.
Li₂YH₆ is predicted to be stable in the I4/mmm phase under high pressures.
High-temperature superconductivity is anticipated due to lithium doping and configuration of hydrogen cages.
Abstract
In this work, we predict that a new hydrogen-rich superconductor, Li₂YH₆, adopts a stable I4/mmm phase in the pressure range of 130–180 GPa, and is similar to YH₄ in terms...
