Principle and application of ball SAW devices

open access: yesElectrical Engineering in Japan, 2007
AbstractA thin beam of waves usually diverges due to diffraction, which is a limitation of any device using such waves. However, a surface acoustic wave (SAW) on a sphere with an appropriate aperture does not diverge but is collimated, realizing ultra‐multiple roundtrips along an equator of the sphere.

Enhancement of Photoemission on p-Type GaAs Using Surface Acoustic Waves

open access: yesSensors, 2020
We demonstrate that photoemission properties of p-type GaAs can be altered by surface acoustic waves (SAWs) generated on the GaAs surface due to dynamical piezoelectric fields of SAWs.
