Description
Hannah Shuttleworth and co-authors squeeze a hydrogen-rich solid until it turns metallic in a 2023 paper. The solid is barium hydride, studied under extreme pressure. Light, X-ray, and resistance tools tracked it together. A richer hydride cousin was made for comparison.
Barium hydride changed structure as pressure climbed. Its band gap closed at the same turning point. Resistance measures confirmed a true metallic state there. Adding more hydrogen pushed the metal point far higher. The richer compound needed much more pressure to metallize. Hydrogen content clearly shapes the electronic behavior. Such hydrides inform the hunt for new superconductors.
