Epitaxial BiFe O3 films were deposited via interface control using SrTi O3 buffer/template layers. The growth orientation relationship was found to be (111) [1 1- 0] BiFe O3 ∥ (111) [1 1- 0] SrTi O3 ∥ (0001) [11 2- 0] GaN, with in-plane 180° rotational twins. The C-V characteristics of a PtBiFe O3 SrTi O3 GaN capacitor exhibited hysteresis with a memory window of ∼3 V at a sweeping voltage of ±30 V. © 2007 American Institute of Physics.}, year = {2007}, journal = {Applied Physics Letters}, volume = {91}, number = {2}, issn = {00036951}, doi = {10.1063/1.2757089}, note = {cited By 52}, language = {eng}, }
