ZnO/(La, Sr) CoO3 (ZnO/LSCO) core-shell composite nanorod arrays have been successfully
synthesized by a sequential combination process of a hydrothermal synthesis followed by a pulsed laser
deposition (PLD) process (or a colloidal deposition process). Compared to the colloidal deposition
process, PLD produces a more uniform and efficient deposition of continuous and mesoporous LSCO
thin films onto ZnO nanorod arrays. During the PLD process, the deposited film uniformity was found
to be dependent on the nanorod diameter, array density, and thus specific surface area of the nanorod
arrays, in addition to the PLD deposition parameters. Field-emission scanning electron microscopy
