An international team of researchers (USA – SLAC National Accelerator Laboratory, Stanford University, Colombia) synthesized high-temperature superconductor BPBO (Barium, Lead, Bismuth, Oxygen) and tested its properties, including transition temperature. The data showed electrons behaving as if they were confined to ultrathin, 2D layers or stripes within the material. The stripes were layers where electrons behave as if they are confined to 2D, puddle-like areas in the material. The distances between the puddles were short enough to allow them to behave like a superconductor. The 2D puddles emerged as the scientists carefully adjusted the temperature and other conditions toward the transition point where the superconductor would become an insulator. The system would form emergent puddles where superconductivity was strong, but the pairs could be broken with much less energy than expected. This offers an additional way to get to these 2D superconducting states. The process is inexpensive and fast…read more. TECHNICAL ARTICLEÂ
