abstract

  • The Poisson's ratio of perovskites with a high degree of anisotropy can change from negative to positive and become much larger than the normally observed range of 0.2-0.4 and even greater than the isotropic upper limit 0.5 along certain crystallographic orientations. These results pave the way for a better understanding of elastic-mediated physical properties of perovskites by engineering the orientation-dependent Poisson's ratios.
