Hence, there still remains substantial "latent" Tc in cuprates. Their proposed doping strategy and superconducting mechanism is not restricted to cuprates and may be exploited in other materials.

Their room-temperature Tc result is based upon four observations:
• Cuprates are intrinsically inhomogeneous on the atomic-scale and are comprised of insulating and metallic regions. The metallic region is formed by doping the material.
• A diverse set of normal state properties are explained solely from the topological properties of these two regions and their doping evolution.
• Superconductivity results from phonons at or adjacent to the interface between the metallic and insulating regions. Transition temperatures Tc ∼ 100 K are possible because the electron-phonon coupling is of longer-range than metals (nearest neighbor).
• These interface phonons explain the observed superconducting properties and lead to their prediction of room-temperature superconductivity.
