Piezoelectric, dielectric and elastic properties of germanium dioxide single crystals

Abstract

/spl alpha/-GeO/sub 2/ crystals were grown and their piezoelectric, dielectric and elastic properties were studied. The crystals have higher piezoelectric constants than most other quartz-like materials. The thickness shear modes have temperature compensated cut near Y-cut. Some electromechanical parameters predicted by correlation with quartz-like crystal structure are suggested.
