Self-Assembled Perovskite-Fluorite Oblique Nanostructures for Adaptive (Tunable) Electronics

The relative concentration of BaTiO3 and CeO2 is shown to control the inclination of composite growth. The oblique composite structures consist of tunable BaTiO3 nanofibers embedded in a CeO2 matrix, which lowers considerably the permittivity while significantly enhancing the tunable response to an electric field. This is of interest in reconfigurable microelectronics.
