Here we report the relationship between local doping and local strain in the cuprate superconductor Bi2Sr2CaCu2O8+x. We use scanning tunneling microscopy to discover that the crucial oxygen dopants are periodically distributed in correlation with local strain. Our picoscale investigation of the intraunit-cell positions of all oxygen dopants provides essential structural input for a complete microscopic theory.en-USHigh-Tc superconductorscupratesBi2Sr2CaCu2O8+xstrainscanning tunneling microscopyJournal Article2015-01-10Ilija Zeljkovic, Jouko Nieminen, Dennis Huang, Tay-Rong Chang, Yang He, Horng-Tay Jeng, Zhijun Xu, Jinsheng Wen, Genda Gu, Hsin Lin, Robert S.
