Superconducting properties of ultrathin Bi2Sr2CaCu2O{8+x} single crystals
Journal article, 2005
We use Ar-ion milling to thin Bi2Sr2CaCu2O8+x (Bi2212) single crystals down to a few nanometers or one to two (CuO2)2 layers. In decreasing the thickness, the superconducting transition temperature gradually decreases to zero and the in-plane resistivity increases to large values indicating the existence of a superconductor-insulator transition in ultrathin Bi2212 single crystals
