Crystal cut angles for lithium tantalate crystal for novel surface acoustic wave devices

摘要

A Lithium Tantalate crystal, defined by the Euler angles lambda ( lambda ) equal to about 0 DEG and mu ( mu ) equal to about 90 DEG with an acoustic wave propagation direction angle theta ( theta ) in the range of plus 130 DEG to plus 150 DEG and preferably equal to about plus 141.25 DEG , offers unique properties for surface acoustic wave device applications.
