Discuss the effect of grain size over the range 50 nm to 50 mm on the real part of the permittivity of bulk polycrystalline BaTiO³. What is the evidence for the ferroelectric state being stable at the smallest grain size and explain why this is relevant to FeRAM technology. Discuss possible reasons why lower permittivity values are found for BaTiO3 in thin film form even when the grain size is the same as that in bulk ceramic form.
