摘要：
An electronic device includes a piezoelectric layer formed of an ordered Langasite structure compound having the formula A3BC3D2E14 wherein A is strontium, B is niobium, C is gallium, D is silicon, and E is oxygen. At least one electrode is connected to the piezoelectric layer and may be configured to define a device, such as a SAW resonator or filter, or a BAW resonator or filter. The ordered Langasite structure compound may have a substantially perfectly ordered structure.
