Non-Superconducting Metals Become Superconducting in Bilayer Heterostructures

Theoretical work by Ummarino & Zaccone shows quantum confinement + proximity effects in metallic bilayers can induce superconductivity in normally non-superconducting metals, using the Eliashberg framework with no free parameters.

LETO/ETO Oxide Superlattices Achieve 20× Thermopower Enhancement via 2D Electron Confinement

LETO/ETO superlattices reach 950 μV K⁻¹ thermopower—20× the 3D value—by exploiting small Bohr radius and Eu 4f-driven confinement to sustain true 2D electron behaviour, doubling gains over SrTiO₃-based systems.
