摘要

研究了ZnO[001]/蓝宝石[001]、AlN[001]/蓝宝石[001]和InSb[001]/Y+128°LiNbO3层状结构中表面声波(SAW)相速度与群速度夹角的色散特性。结果表明，该色散在500mhz频段内可达到30°。

Dispersion of the group velocity direction of surface acoustic waves in layered structures

The dispersion of an angle between the phase velocity and the group velocity of surface acoustic waves (SAW) in layered structures ZnO[001]/Sapphire[001], AlN[001]/Sapphire[001] and InSb[001]/Y+128°LiNbO3 was studied. It was shown that this dispersion can achieve 30° in the frequency band of 500 MHz.
