摘要

Rhombohedral relaxor single crystals are a class of materials that includes PZN-PT and PMN-PT in a certain range of compositions. This work presents an approach to predicting the physical properties of relaxor single crystals with an engineered domain state. A model based on properties of crystal variants and volume averaging indicates large piezoelectric coefficient d_(31) (690 Pc/N) and d_(32) (-1670 Pc/N) for the <110> cuts and a value over 4000 Pc/N for d_(15) and the existence of d_(16) with a value as large as -2300 Pc/N in <111> orientation cuts. The predictive capability of the approach results in a computational tool for the design of engineered domain states with properties optimized for specific applications. This has resulted in the identification of a crystal cut optimized for actuator and sensor applications that utilizes the transverse mode piezoelectric coupling coefficients (d_(31)) and d_(32).
