Abstract

New values for the elastic and piezoelectric constants of Bi 12GeO20 and for their temperature derivatives are reported. With these new constants, the predicted value of Δv/v for acoustic surface waves is significantly increased. This prediction has been verified by measurements of the acoustic surface-wave velocity on the metallized and unmetallized (001) surface of Bi12GeO20 and by comparing the observed values with theory. On the (001) plane, the maximum Δv/v occurs in the 〈110〉 direction. The predicted Δv/v is 66×10-4 and the experimentally observed value is (77±15)×10-4.
