Pristine Monolayer Cuprate Superconductor Fabricated

Researchers have fabricated a high-quality monolayer cuprate superconductor featuring a single CuO2 plane to study quantum critical phenomena.

• A pristine monolayer cuprate superconductor with a single CuO2 plane was successfully fabricated.
• Researchers identified two quantum critical phenomena between the Mott insulating and superconducting phases.
