Microwave Conductivity of Ferroelectric Domains and Domain Walls in Hexagonal Rare-earth Ferrite
Xiaoyu Wu, Kai Du, Lu Zheng +3
We report the nanoscale electrical imaging results in hexagonal single crystals using conductive atomic force microscopy (C-AFM) and scanning microwave impe…
Visualization of Surface-acoustic-wave Potential by Transmission-mode Microwave Impedance Microscopy
Lu Zheng, Di Wu, Xiaoyu Wu +1
Elastic waves propagating in piezoelectric materials are accompanied by a time-varying electric potential, which is of critical importance for acousto-electronic applications. The…
Interferometric Imaging of Nonlocal Electromechanical Power Transduction in Ferroelectric Domains
Lu Zheng, Hui Dong, Xiaoyu Wu +5
The electrical generation and detection of elastic waves are the foundation for acousto-electronic and acousto-optic systems. For surface-acoustic-wave devices, micro-/nano-electro…
Quantitative Measurements of Nanoscale Permittivity and Conductivity Using Tuning-fork-based Microwave Impedance Microscopy
Xiaoyu Wu, Zhenqi Hao, Di Wu +5
We report quantitative measurements of nanoscale permittivity and conductivity using tuning-fork (TF) based microwave impedance microscopy (MIM). The system is operated under the d…
