Thickness Dependence of c/a Polytwin Structures Observed in Epitaxial Oxide Ferroelectric Thin Films
Polytwin Structures Epitaxial Oxide Ferroelectric Thin Films
2010/4/15
Ferroelectric or ferroelastic epitaxial films undergoing a cubic-to-tetragonal phase transformation usually relax the resultant strain energy due to lattice misfit by forming a polytwin (polydomain) s...
