Abstract

Following our previous work on the converse piezoelectric constant- in epitaxial ferroelectric films for MEMS actuator applications, the orientation dependence of the direct piezoelectric constants , and are generally formulated, which can help to predict and optimize the performance of piezoelectric MEMS sensor devices based on ferroelectric thin films. Numerical results are obtained and discussed for Pb(ZrxTi1-x)O3 thin films grow on Si substrates with various compositions and structures.

Pseudo-tetragonal elastic compliances were given as function of x for bulk Pb(ZrxTi1-x)O3 materials near the morphotropic phase boundary (x=0.48~0.6). For rhombohedral PZT (x≥0.52), the compliance data were obtained by the following procedures as described in Ref. 18: the average value of and was used as , the average value of and was used as , and the average value of and was used as in the pseudo-cubic coordinate system. Then the cubic axis system was rotated to the rhombohedral axis system and the elastic compliance data were obtained by rules of tensor operations12 for the calculation of elastic modulus.Google Scholar
