Synthesis of (SrLaF) FeAs superconducting films by pulsed laser deposition Relationship between photo excited lights and crystalline of the films Satoshi Kurumi, Yoshiki Takano, and Kaoru Suzuki-Department of Electrical Engineering and Department of Physics We have tried to prepare superconducting (SrLaF)FeAs thin films by the photo excited pulsed laser deposition (PE-PLD). In this paper we describe pulsed laser deposition of thin superconducting films of HojBa2Cu3O7 _ x and Y1Ba2Cu3O7_x on a variety of substrates (SrTiO3, A12O3, and SiO2 on Si). In a previous paper, we reported a lack of stoichiometry in oxygen-annealed thin films formed by pulsed laser ablation of Y1Ba2Cu3O7_ * at low fluences Here the.

Thin-film materials with PLD. Pulsed Laser Ablation Although the underlying ablation process is complex, PLD is conceptually and experi- mentally simple. An ultraviolet (UV) pulsed laser beam (pulse duration, 10 to 50 ns) is focused with an energy density Ed of 1 to 5 J/cm2 onto a rotating polycrystalline target (Fig.
Pulsed laser deposition (PLD) is a conceptually and experimentally simple yet highly versatile tool for thin-film and multilayer research. Its advantages for the film growth of oxides and other chemically complex materials include stoichiometric transfer, growth from an energetic beam, reactive deposition, and inherent simplicity for the growth of multilayered structures.

For thin film synthesis of complex oxides, one of the most important issues has always been how to oxidise the material. For a technique like pulsed laser deposition, a key benefit is the relatively high oxygen background pressure one can operate at, and therefor oxidation should be relatively straightforward.
