Lithium iodate - A new material for surface acoustic wave applications
Abstract
Lithium iodate (LiIO3) is proposed as a new material for possible use in surface acoustic wave (SAW) devices. The variation of the SAW velocity, an estimate of the electromagnetic to acoustic coupling, the temperature coefficient of delay (TCD), and the power flow angle have been theoretically predicted for the standard crystallographic cuts. This material is shown to have more than 1.5 times the coupling of LiNbO3, SAW velocities only slightly higher than Bi12GeO20, low temperature coefficients of delay, and low power flow angles.
