Prediction of ternary superconducting YCH12 using a novel solid hydrogen source under high pressure

Hydride superconductor YCH 12 , which can be formed using a new hydrogen source adamantine, was explored using DFT calculations. The results revealed a maximal T c ∼112 K in the triclinic phase at 180 GPa attributed to a strong electron–phonon coupling around 3.80.
