Elastic, piezoelectric, and dielectric properties of α-GeO2 single crystals

Abstract

The elastic, piezoelectric, and dielectric characteristics of α-GeO 2 crystals are studied at room temperature. The measurements were performed by the resonance method on crystals grown on α-quartz seeds from solutions in the recirculating mode. In germanium dioxide crystals, the piezoelectric moduli have high values. The characteristic features of variations of the electromechanical and elastic properties in crystals with the quartzlike structure observed earlier are confirmed.
