Abstract

Doped Sr2IrO4 is of interest because of its close similarities to La2CuO4, a parent compound of the cuprates. Nelson et al. reveal the intrinsic evolution of its electronic structure with hole doping by avoiding the strong in-plane disorder introduced by previously used chemical substitutions.
