Variation of Contact Resonance Frequency during Domain Switching in PFM Measurements for Ferroelectric Materials
Yue Liu, Yao Sun, Wanheng Lu +5
Piezoresponse Force Spectroscopy (PFS) is a powerful method widely used for measuring the nanoscale ferroelectric responses of the materials. However, it is found that certain non-…

Unravelling the origin of piezo/ferro-electric properties of metal-organic frameworks (MOFs) nanocrystals
Yao Sun, Junfeng Gao, Yuan Cheng +2
Metal-organic framework (MOF) UiO-66 nanocrystals were previously believed to be piezo/ferro-electrically inactive because of their centrosymmetric lattice symmetries (Fm-3m (225))…
