Seemingly contradictory reports on polar domains and their origin have surrounded the controversial discussion about the ferroelectricity of the methyl ammonium lead iodide (MAPbI3) thin films that are commonly employed in perovskite solar cells. In this work, microscopic modulations of the polar domain patterns upon application of an electric poling field are correlated with macroscopic changes to the currents through the MAPbI3 layer. Piezoresponse force microscopy is used to monitor the widening, narrowing, generation or extinction of polar domains, as well as shifts of the domain walls at room temperature under an in‐plane electric poling field that is applied between two laterally organized electrodes. This poling leads to a net polarization of individual grains and the thin film itself. Macroscopically, this net polarization results in a persistent shift of the diode characteristics that is measured across the channel between the electrodes. Both the modulation of the polar domains upon electric poling and the concurrent persistent shift of the electric currents through the device are the unambiguous hallmarks of ferroelectricity, which demonstrate that MAPbI3 is a ferroelectric semiconductor. 相似文献

A series of commercially available nanosized barium titanates has been investigated with respect to their use as high-k-ceramic
filler in polymer based composites with improved dielectric properties. The thermal treatment of the barium titanate powders
at 1,000°C causes a significant increase of the composite’s permittivity. X-ray diffraction experiments prior and after heat
treatment revealed that the barium titanate with smallest particle size and the largest specific surface area possesses the
thermodynamically unstable cubic phase. In case of the other investigated barium titanates the crystal lattice is distorted.
Thermal treatment induces the phase change into the tetragonal one and crystal lattice relaxation enabling higher permittivity
values. Composites with a solid load around 78 wt% with a bimodal particle size distribution show high permittivities around
50 and a low loss factor around 5‰ suitable for the realization of embedded capacitors via screen printing or tape casting. 相似文献
