New light-based studies of Bi2212 superconductors reveal key insights into high-temperature superconductivity, advancing the quest for room-temperature applications. Copper-oxide (CuO2) superconductors, including Bi2Sr2CaCu2O8+δ (Bi2212), are notable for their unusually high critical temperatures. Previous studies using optical reflectivity measurements revealed that Bi2212 exhibits strong optical anisotropy, meaning its optical properties change depending on the direction of […]
