“…According to the behavior of the dielectric material, electromechanical resonances were observed in the impedance spectra only when, in addition to the ac measuring voltage, a dc bias voltage was applied. 8 The applied dc voltage was 150 V, which was about three times higher than the rated voltage of the samples. This high bias voltage was necessary to reach the operation point of the device, in which sufficient electrical energy is converted into mechanical vibration because of the piezoelectric behavior.…”

“…Like relaxor materials, it is not possible to permanently pole the ceramic. 8 Therefore, if a high bias field is applied, a significant change in the mechanical strain is achieved because of additionally applied ac voltage. Consequences of this electrical-mechanical coupling at high bias fields are resonances in the electrical impedance spectra, as shown later.…”

The opportunities are introduced to calculate the electrical, mechanical, and thermal couplings of ceramic multilayer capacitors (MLCs) with the finite-element method. The results may lead to improvements in the production, integration, and operation of MLCs. In this paper, a comparison is given of calculations and measurements of electromechanical resonances in the impedance spectra of MLCs. The simulation of defective capacitors with three different types of assumed faults reveals the changes in the impedance spectra due to these defects. This allows the prediction of flaws in MLCs based on measurement of the impedance spectra.

Nonlinear dynamics underpin a vast array of physical phenomena ranging from interfacial motion to jamming transitions. In many cases, insight into the nonlinear behavior can be gleaned through exploration of higher order harmonics. Here, a method using band excitation scanning probe microscopy (SPM) to investigate higher order harmonics of the electromechanical response, with nanometer scale spatial resolution is presented. The technique is demonstrated by probing the first three harmonics of strain for a Pb(Zr1-xTix)O3 (PZT) ferroelectric capacitor. It is shown that the second order harmonic response is correlated with the first harmonic response, whereas the third harmonic is not. Additionally, measurements of the second harmonic reveal significant deviations from Rayleigh-type models in the form of a much more complicated field dependence than is observed in the spatially averaged data. These results illustrate the versatility of nth order harmonic SPM detection methods in exploring nonlinear phenomena in nanoscale materials.
