Low-Temperature Sputtering Deposition of Aligned Polycrystalline CaCu_3Ti_4O_(12) Nanorods

摘要

Vertically aligned polycrystalline CaCu_3Ti_4O_(12) nanorods were obtained by rf sputtering at low substrate temperatures. The rods grow by electrostatic attraction and aggregation of charged clusters, independently of the substrate used. These nanostruc-tures exhibit a strong nonlinear current × voltage behavior and high losses during cyclic testing, indicating a combination of Schottky's barrier and Joule's heating effects.
