Description
Nanometer-scale modulations can spontaneously emerge in complex materials when multiple degrees of freedom interact. In this talk, I will demonstrate that SrTiO₃ lies near an incipient structurally modulated phase. I will then explore how Ca doping and an applied electric field influence this phase, revealing that it cooperates with—rather than competes against—the other lattice instabilities in SrTiO₃.
