Temperature Dependence of Rayleigh Wave Delay Line Materials.
Abstract
The variation of surface acoustic wave delay time with temperature was measured for many orientations of the commonly used piezoelectric substrate material and some uncommon ones as well as for composite devices with oriented ZnO overlay films. The single crystal materials studied included: quartz, LiNbO3, LiTaO3, Bi12GeO20, ZnO, and TeO2. Accurate measurements of electromechanical coupling constant were also performed using two sensitive techniques. The mass loading of aluminum thin films on various substrates was experimentally determined. A brief investigation into the viability of electrostriction as a mechanism for surface acoustic wave transduction was performed. Analysis and measurements of temperature effects on chirp pulse compression signal processing devices was performed.
