Superconducting and electro-optical thin films prepared by pulsed laser deposition technique

Optical Properties of Nitrogen-Substituted Strontium Titanate Thin Films Prepared by Pulsed Laser Deposition

Perovskite-type N-substituted SrTiO3 thin films with a preferential (001) orientation were grown by pulsed laser deposition on (001)-oriented MgO and LaAlO3 substrates. Application of N2 or ammonia using a synchronized reactive gas pulse produces SrTiO3-x:Nx films with a nitrogen content of up to 4.1 at.% if prepared with the NH3 gas pulse at a substrate temperature of 720 °C. Incorporating nit...

Optical properties of LuFeO3 thin films prepared by pulsed laser deposition

The LuFeO 3 thin films were successfully prepared by pulsed laser deposition on silicon and LaNiO 3-coated silicon substrates, respectively. The crystalline structure of the films has been studied by x-ray diffraction and indicated that all the films were well-crystallized. Atomic force microscope was used to characterize the surface morphology of the films and the surface was uniform and dense...

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...

Li-rich Thin Film Cathode Prepared by Pulsed Laser Deposition

Li-rich layer-structured cathode thin films are prepared by pulsed laser deposition. X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS) and electrochemical testing in half battery cells are used to characterize crystal structure, surface morphology, chemical valence states and electrochemical performance of these thin films, resp...
