Nanoscale Non-Destructive Ferroelectric Characterization with Non-Contact Heterodyne Electrostrain Force Microscopy
Qibin Zeng, Qicheng Huang, Hongli Wang +5
Perceiving nanoscale ferroelectric phenomena from real space is of great importance for elucidating underlying ferroelectric physics. During the past decades, nanoscale ferroelectr…
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-…
Multiple-Modes Scanning Probe Microscopy Characterization of Copper doped Zinc Oxide (ZnO:Cu) Thin Films
Juanxiu Xiao, Tun Seng Herng, Jun Ding +1
This paper presents multiple-modes Scanning Probe Microscopy (SPM) studies on characterize resistance switching (RS), polarization rotation (PO) and surface potential changes in co…
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))…
Microstructural Evolution of Charged Defects in the Fatigue Process of Polycrystalline BiFeO3 Thin Films
Qingqing Ke, Amit Kumar, Xiaojie Lou +4
Fatigue failure in ferroelectrics has been intensively investigated in the past few decades. Most of the mechanisms discussed for ferroelectric fatigue have been built on the "hypo…
Origin of the Enhanced Polarization in La and Mg Co-substituted BiFeO3 Thin Film during the Fatigue Process
Qingqing Ke, Amit Kumar, Xiaojie Lou +2
We have studied the polarization fatigue of La and Mg co-substituted BiFeO3 thin film, where a polarization peak is observed during the fatigue process. The origin of such anomalou…
Oxygen-vacancy-mediated Negative Differential Resistance in La and Mg co-substituted BiFeO3 Thin Film
Qingqing Ke, Amit Kumar, Xiaojie Lou +2
The conductive characteristics of Bi0.9La0.1Fe0.96Mg0.04O3(BLFM) thin film are investigated at various temperatures and a negative differential resistance (NDR) is observed in the…
