- PFM-Piezoelectric force microscopy
- Description
- In this Figure on the left side PFM image of lead halide perovskite film is observed that the piezo signal is sharply observed on the grain boundaries which have most deficient structure and disorder, while the grain have inversion symetry and do not show piezoelectricity, at the same time this image is really lookalike a photography of dried lake in Bolivia desert that has formed exactly similar structure in such a large scale
