Functional interfaces are discussed as a source of multiferroic behaviour and (super-)conductivity. Superconductivity, ferroelectricity and ferromagnetism are common features in bulk materials while ferroelastic twin boundaries are now understood to show the same properties only inside twin walls but not in the bulk. Functionality is hence confined to very thin layers, which, in turn, can be shifted, bent and dynamically excited. These new effects were classified as ‘Domain Boundary Engineering’ in the hope that soon we will be able to apply such functional twin boundaries in an engineering fashion to produce high-density memory devices, electronic and thermal switches and medical delivery systems where the diffusion of molecules can be pinpointed along twin boundaries with so-far unknown accuracy. In this chapter the advances of research on functional twin boundaries are reviewed and new directions for research are identified.
