Laser ablation, low temperature-fabricated yttria-stabilized zirconia oriented films

Formation of for example yttria stabilized zirconia films of significant 001 orientation on a variety of substrates including amorphous material and room temperature limited material is disclosed. The yttria stabilized zirconia film formation is achieved using pulsed laser ablation of a polycrystalline yttria stabilized zirconia target source while the substrate is electrically biased, disposed at a selected angle and maintained at substantially room temperature in the presence of an argon atmosphere. The film formation uses low bias voltage, requires no ion beam apparatus and employs low temperatures sufficient only to enable process stabilization. Film formation is accomplished in a step sequence wherein each step responds to temporal and spatial component segregations occurring in a laser-ablated ion plume.
