Preparation and Structure Characterization of CeO_2 Films on the Stainless Steel Substrates Deposited by Laser Ablation with Ar~+ Ion Beam Assistance

CeO2 films were deposited by pulsed laser ablation on stainless steel substrates at room temperature with the Ar+ ion beam assistance. The results show that when the CeO2 films are deposited directly on the stainless steel substrates, the desired (001)-normal textured films achieved, but there is no evidence for alignment of in-plane crystal axes. Further experimental results indicate that CeO2/YSZ(Yttria-Stabilized Zirconia)/stainless steel films deposited under the same conditions are not only normal orientation to the substrate's surface, but also highlyin-plane textured.
