摘要:
Elements and methods for forming elements that operate with acoustic waves are disclosed. The element includes a piezoelectric electric substrate that has a first thermal coefficient of expansion, electrically conducting element structures on an upper side of the substrate, a compensation layer on an underside of the substrate, and an SiO2 layer over the element structures.

摘要:
An electroacoustic component includes a substrate that includes a quartz single crystal. The quartz single crystal has a first Euler angle λ: −5°≦λ≦5°, a second Euler angle μ, and a third Euler angle θ. A contiguous region of the quartz single crystal has the following vertices Pi(μi, θi): (23°, 20°), (60°, 17°), (110°, 30°), (105°, 42°), (60°, 30°), (23°, 25°).
