Abstract: We present a comparative study on the ferroic properties of complex oxides nano-structured in nano particles (3D), needles (2D), and films (1D). Nanovaractors of barium titanate (BaTiO3) and barium strontium titanate (BST) thin films have been successfully fabricated through advanced E-beam lithography and inductively coupled plasma (ICP) dry etch. Additionally, the superparaelectric (SPE) phenomena of ferroelectric materials have been discussed. Finally, we have explored the solutions to discover the superparaelectric phase through temperature dependence and electrical property tests.
