| Abstract: | Transition temperatures between tetragonal and monoclinic polymorphs of ZrO2 nanoparticles, thin films and nanostructured materials are calculated by considering energetic contributions of surface (interface) energy and surface stress on total Gibbs free energy. The transition temperatures drop as the size of the nanocrystals decreases, which is consistent with available results. |
