Phase coexistence in ferroelectric solid solutions: Formation of monoclinic phase with enhanced piezoelectricity

Blog Article

Phase morphology and corresponding piezoelectricity in ferroelectric solid solutions were studied by using a phenomenological theory with the consideration of phase coexistence.Results have shown that phases with similar energy potentials can coexist, thus induce bachelorette-supplies interfacial stresses which lead to the formation of adaptive monoclinic phases.A new tetragonal-like monoclinic to rhombohedral-like monoclinic phase transition was predicted in a shear stress state.Enhanced piezoelectricity can be achieved by manipulating the stress state close to a critical stress field.

Phase coexistence is universal in ferroelectric solid solutions and may provide a way to optimize ultra-fine structures and proper stress states Love Eggs to achieve ultrahigh piezoelectricity.
