Superconducting MgB2 thin films by pulsed laser deposition

Pulsed Laser Deposition of Hydroxyapatite Thin Films

Pulsed laser deposition of VO2 thin films

High quality vanadium dioxide ~VO2! thin films have been successfully deposited by pulsed laser deposition without postannealing on ~0001! and ~101̄0! sapphire substrates. X-ray diffraction reveals that the films are highly oriented with ~010! planes parallel to the surface of the substrate. VO2 thin films on ~0001! and ~101̄0! substrates show semiconductor to metal transistions with electrical r...

In-situ growth of superconducting SmO1−xFxFeAs thin films by pulsed laser deposition

Oxypnictide thin film growth by pulsed laser deposition (PLD) is one of many insufficiently resolved issues in the research of iron-based superconductors. Here we report on the successful realization of superconducting SmO1-xFxFeAs oxypnictide thin film growth by in-situ PLD on CaF2 (fluorite) substrates. CaF2 acts as fluorine supplier by diffusion and thus enables superconducting oxypnictide t...

Growth of superconducting (Hg,Re)Ba2CaCu2Oy thin films on Ag by pulsed laser deposition

(Hg,Re)Ba2CaCu2Oy thin films have been fabricated on Ag by reacting laser deposited ReBaCaCuO precursor films with CaHgO2 in sealed quartz tubes. The as-prepared films exhibit excellent phase purity and c-axis texture, characterized by an onset superconducting transition temperature (Tc) of 124 K. The microstructures of the films examined by environmental scanning electron microscope revealed H...

Investigation of Magnetite Thin-Films Produced by Pulsed Laser Deposition

Thin-films of magnetite, F@04 have been produced by the XeCl excimer laser ablation of both Fe304 and metallic Fe targets. The ablation of metallic Fe has been shown to produce about two orders of magnitude smaller concentration of boulders than the ablation of bulk magnetite. The use of single-crystal, latticematching substrates was found to be necessary at lower fluences (1 3 J cm-') for the ...
