Electron Devices on Piezoelectric Semiconductors: A Device Model

IEEE Transactions on Sonics and Ultrasonics, 1984
The effects of acoustic waves on the terminal characteristics of electron devices on piezoelectric semiconductors are considered. The piezoelectric displacement charge is regarded as a time- and space-vary ing perturbation of the doping density of the semiconductor.

Piezoelectric thin film devices

IEEE 1991 Ultrasonics Symposium, 2002
A new class of thin-film device structures has become available with the development of thin-film piezoelectric films by sol gel methods or by magnetron sputtering. In particular, sol gel techniques for ceramics such as lead zirconate titanate allow the fabrication of films of 1-4- mu m thickness on surfaces of complex shape with crack propagation ...

CAD for circuits with piezoelectric devices

Proceedings of the 2000 IEEE/EIA International Frequency Control Symposium and Exhibition (Cat. No.00CH37052), 2002
During the last decade commercial software packages for circuit design matured concurrent with PC operating systems. Although optimized for general-purpose design, when used imaginatively, they are useful for circuits that employ piezoelectric devices. This paper illustrates CAD for such circuits with simple examples as the vehicle. The GENESYS 7 suite

Piezoelectric Power-Harvesting Devices

2017
Piezoelectric power-generation devices can be divided into two categories: (a) self-energizing devices (self-powered solely by the static or dynamic movement of piezoelectric devices), and (b) energy-harvesting devices that are attached to existing structures that vibrate during operation of the structure. Both of these devices capture otherwise wasted
