Dissertation of Zhuopeng Tan

Main tasks of our research include: (1)exploring
optimum growth conditions for PLD deposition of
self-assembled nanophase PbTiO3-CoFe2O4 films with
different compositions and orientations; (2)analyzing
morphologies and nanostructures of the two-phase
films to clarify relative effects of elastic energy
and interface energy on the self-assembled film
formation; (3)investigating stress state and
relaxation of stresses arising as a result of a
paraelectric-ferroelectric transformation in PbTiO3;
(4)exploring ferroelectric state in the confined
PbTiO3 nanophase in the films with {110} and {111}
orientations.
