Title:
表面音響波の速度の電界制御
Document Type and Number:
Japanese Patent JP5121298
Kind Code:
B2
Abstract:
An apparatus in one example comprises a piezoelectric layer, a first electrode along a first side of the piezoelectric layer, and a second electrode along a second side of the piezoelectric layer. The first and second electrodes are adapted to receive a voltage bias to create an electric field in the piezoelectric layer that controls an acoustic velocity of a surface acoustic wave.
