Semiconducting Films: Electric and Mechanical Switching of Ferroelectric and Resistive States in Semiconducting BaTiO3–δ Films on Silicon (Small 39/2017)

In article number 1701614, Andrés Gómez, Adrián Carretero-Genevrier, and co-workers report a novel approach to integrate epitaxial nanostructured n-type semiconducting BaTiO3−δ films on silicon by combining molecular beam epitaxy and a water-based chemical method. This growth strategy results into epitaxial BaTiO3−δ/La0.7Sr0.3MnO3/SrTiO3/Si columnar nanostructures that enhance the flexoelectric response of the system and enables the control of the ferroelectric polarization and local conductivity (resistive switching) of this functional oxide upon applying a mechanical load.
