- The paper shows a new method for increasing Tc in cuprate superconductors. For the first time, Tc is enhanced easily in more than a single unit cell, using nanocomposite films that induce unique 3D strain states. In La2CuO4+d, Tc is increased to 50K from the usual ~20K in standard films. Also, the need for complex oxygenation using ozone was eliminated. No group has previously demonstrated 3D structural tuning for increasing Tc or for enhancing oxygenation. Funding from Office of Naval Research Global, N62909-18-1-209, (USD280k) and Leverhulme Trust, RPG-2020-041, (GBP380k) arose from this work.
