Overview

Explores how pressure influences superconducting properties in Li-Al-H systems, suggesting new design strategies for high-Tc materials.

Key Points

  • To investigate the mechanisms of high-temperature superconductivity in Li-Al-H systems under high pressure.
  • Conducted structural searches of Li-Al-H materials at 200 GPa.
  • Predicted stable phases, Pm3−m Li3AlH4 and P4/mmm LiAlH5.
  • Analyzed electron-phonon coupling and electronic density of states under varying pressures.
  • Li3AlH4 exhibits a critical temperature of 78.32 K at 350 GPa.
  • LiAlH5 reaches a maximum critical temperature of 128.96 K at 100 GPa.
  • Distinct pressure responses of electronic density of states influence superconducting properties.
