Investigating the Electromechanical Behavior of Unconventionally Ferroelectric Hf _0.5 Zr _0.5 O ₂ ‐Based Capacitors Through Operando Nanobeam X‐Ray Diffraction

The effect of Bragg reflectors on the electromechanical performance of parallel-plate ferroelectric capacitors

Parallel-plate capacitors based on ferroelectric thin films are considered as high density capacitors and varactors. Due to the small thickness of the ferroelectric films, typically less than 1.0 μm, high electric fields are generated even at relatively low voltages inducing piezoelectric effect associated with electrostriction. This induced piezoelectric effect has negative impact on ferroelec...

Photocathodic behavior of ferroelectric Pb(Zr,Ti)O(3) films decorated with silver nanoparticles.

ITO/Pb(Zr,Ti)O(3) contacts and Ag nanoparticles were used to construct a novel ferroelectric film photocathode exhibiting a stable short-circuit photocurrent of 110 μA cm(-2) and an open-circuit voltage of 0.76 V under 100 mW cm(-2) Xe-lamp illumination and zero-bias versus SCE.

Mechanical stress effect on imprint behavior of integrated ferroelectric capacitors

Stress-induced changes in the imprint and switching behavior of ~111!-oriented Pb(Zr,Ti)O3 ~PZT!-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d33-loop measurements in individual 131.5-mm 2 capacitors before and after stress application, generated by substrate bending, provided direct experimental evidence of stress-induc...

Comprehensive Electromechanical Analysis of MEMS Variable Gap Capacitors

This paper presents a comprehensive case study on electro-mechanical analysis of MEMS[1] variable capacitors. Using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. The analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. A complete set of equations defining dynamic behavior of ...
