Abstract

Nanorods composed of complex oxides have been synthesized using hydrothermal and sol-gel methods, but pulsed-laser deposition (PLD) provides precise, layer-by-layer control of growth, and is the method of choice for synthesizing complex structures. However, producing complex-oxide nanorods by PLD has proved elusive.

Here we report on our efforts to produce nanorods composed of the best-understood complex oxide, strontium titanate (STO). The results suggest it is indeed possible to produce STO nanorods via PLD by using a template of MgO nanorods.
