Fabrication of Isolated Ferroelectric Nanostructures
Abstract
In this report, we explore the possibilities of the fabrication and characterization of ferroelectric nano-structures by various methods. Techniques include the self-assembly route and direct electron beam lithography. The chemical self-assembly route, which adopted the microemulsion-mediated synthesis, appeared to be very encouraging for producing very small monodispersed nano particles and powders, with sizes of 10-60 nm. The possibility to form a two dimensional arrangement of these micro droplets was explored with a suitable choice of the substrate material, and the method of coating. For the patterns prepared by the e-beam technique, a strong coupling between two closely spaced nano elements was observed, the spacing between them was found to be the key factor in tailoring their interaction, i.e., whether they would arrange themselves in rod-like pattern or a two dimensional array of isolated squares or circles.
