The relative concentration of BaTiO 3 and CeO 2 is shown to control the inclination of composite growth. The oblique composite structures consist of tunable BaTiO 3 nanofibers embedded in a CeO 2 matrix, which lowers considerably the permittivity while significantly enhancing the tunable response to an electric field. This is of interest in reconfigurable microelectronics.
