Superconductor-insulator transition in space charge doped one unit cell Bi2.1Sr1.9CaCu2O8+x
Abstract
Previous work on critical scaling at the superconductor-to-insulator transition has shown variations across different materials. Here, the authors use a space charge doping technique to tune the transition in a single layer cuprate sample and present evidence of the universal scaling behaviour.
