摘要：

This work investigates the effects of anisotropic epitaxial strains on the microwave frequency dielectric response of BST (60/40) thin films. Dielectric properties such as permittivity and tunability along the <-110 >, <-111 > and < 001 > crystallographic directions correlate well with the variation of elastic strain energy as a function of film thickness. We demonstrate unequivocally that the maximum permittivity and tunability is obtained along a crystallographic direction where the strain is a minimum.
