Room-temperature superconductivity: Researchers uncover optical secrets of Bi-based superconductors
Copper-oxide (CuO2) superconductors, such as Bi2Sr2CaCu2O8+δ (Bi2212), have unusually high critical temperatures. Optical reflectivity measurements of Bi2212 have shown that it exhibits strong optical anisotropy. However, this has not been studied through optical transmittance measurements, which can offer more direct insights into bulk properties. ⌘ Read more
