In finely layered ferroelectric superlattices, the polarization domain configuration is determined by a complex interplay of strain, electrostatics and other local distortions of the crystal lattice. Here I will discuss a number of experimental works we have performed to try to better understand these effects and harness them to produce more effective functionality in ferroelectric devices. A particular emphasis is on the development of domain structure during the growth of our artificially layered  structures, which we have studied using in-situ synchrotron x-ray diffraction.
