Researchers at GW have developed a novel method to enhance the piezoelectric property of weak or none piezoelectric materials(GaAs) using surface acoustic waves and strong piezoelectric material (ZnO). This will help in generating piezoelectric effect on materials that can be used in electronic applications and optoelectronic devices.
This disclosed invention can be implemented as a device/method. The method is made up of SAW(Surface acoustic wave) device implemented in an island format which has been successfully tested in the lab on a highly doped P-Type GaAs substrate which has enhanced the piezoelectric properties of the substrate.
Advantages

Applications
- Photodetectors, photomultipliers
- Electron microscope
- Nanowires/nanotube applications
- SAW- Tunable crystal phase superlattices
- Advanced memory devices
- High brightness unpolarized electron sources for high energy physics
