Fecha de publicación: | 19-sep-2016 | Editor: | American Institute of Physics | Citación: | Applied Physics Letters 109(12): 122903 (2016) | Resumen: | The integration of epitaxial BaTiO3 films on silicon, combining c-orientation, surface flatness, and high ferroelectric polarization is of main interest towards its use in memory devices. This combination of properties has been only achieved so far by using yttria-stabilized zirconia buffer layers. Here, the all-perovskite BaTiO3/LaNiO3/SrTiO3 heterostructure is grown monolithically on Si(001). The BaTiO3 films are epitaxial and c-oriented and present low surface roughness and high remnant ferroelectric polarization around 6 μC/cm2. This result paves the way towards the fabrication of lead-free BaTiO3 ferroelectric memories on silicon platforms. | Descripción: | Scigaj, M. et al. | Versión del editor: | http://dx.doi.org/10.1063/1.4962836 | URI: | http://hdl.handle.net/10261/137196 | DOI: | 10.1063/1.4962836 | ISSN: | 0003-6951 |
