Nanoscale control of oxides by laser ablation : design and applications

In this paper, we demonstrate the capability of the pulsed laser deposition techniques for designing the novel/new multifunctional materials which are usually unachievable by classical synthesis routes. It details about the sequential growth of various materials in form of superlattices by controlling them at nano-scale level in order to design the new structures with multifunctional properties. A discussion on the issues related with role of thickness of the oxides in designing the novel materials viz ., multiferroics, together with how one can enhance the multifunctionality by controlling the size of the oxides at nano-level are presented. Also a brief comments on the issues related to the growth of the nano-oxides by pulsed laser deposition is discussed.
