Graphical Abstract
The polarization of PbTiO3/SrTiO3superlattices is experimentally tuned from 0–60 μC/cm–2 and the transition temperature from room temperature to 1000 K while maintaining a perfect crystal structure and low leakage currents (see figure). A simple model based on Landau theory is developed as a guide for the straightforward production of samples with ferroelectric properties designed for particular applications.
