[Press Release]Unveiling an anomalous electronic state opens a pathway to room-temperature superconductivity
Crystal and electronic structures in the triple-layer cuprate superconductor
Triple-layer cuprate superconductors have three copper oxide planes, two outer (orange) and one inner (blue) plane (left). These two types of copper (Cu)-oxygen (O) planes show two quasiparticle bands as observed in the high-resolution angle-resolved photoemission spectroscopy (right).

Release Summary
Superconductive materials can conduct electricity with no resistance, but typically only at very low temperatures. Realizing superconductivity at room temperature could enable advanced, energy-efficient electronics and other technologies. Now, an international research team is one step closer to such an achievement. The researchers made the first observation of a special electronic state known as a “nodal metal,” which provides more insight into electronic behavior at different temperatures, in a multilayer system comprising copper and oxygen.
The team, which includes researchers based in Japan, Taiwan and the United States, published their results on Oct. 27 in Nature Communications.
