  • Amorphous to crystalline phase transition in pulsed laser deposited silicon carbide 
    Tabbal M.; Said A.; Hannoun E.; Christidis T. (AMSTERDAMPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2007)
    SiC thin films were grown on Si (1 0 0) substrates by excimer laser ablation of a SiC target in vacuum. The effect of deposition temperature (up to 950 °C), post-deposition annealing and laser energy on the nanostructure, ...
  • Pulsed laser deposition of Tungsten thin films on graphite 
    Kassem W.; Tabbal M.; Roumie M. (STAFA-ZURICHLAUBLSRUTISTR 24, CH-8717 STAFA-ZURICH, SWITZERLAND, 2011)
    Thin coatings of Tungsten were deposited on substrates fabricated by pre-depositing graphite thin layers on Si(100) wafers. We ablate pure W target using a 20 ns KrF excimer laser (248 nm) in an Ar ambient. The effect of ...
  • Study of manganese oxide thin films grown by pulsed laser deposition 
    Isber S.; Majdalani E.; Tabbal M.; Christidis T.; Zahraman K.; Nsouli B. (LAUSANNEPO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009)
    In this paper, we report on the growth of manganese oxides thin films by Pulsed Laser Deposition using an MnO target at various oxygen pressures and substrate temperatures ranging from 550 to 800 °C. Grazing Incidence X-Ray ...
  • Superconducting properties of Tl-2223 phase substituted by iron 
    Isber S.; Awad R.; Tabbal M.; Abou-Aly A.I.; Nsouli B.; Zahraman K.; Mansour A.; Farj A. (BRISTOLDIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2006)
    Bulk superconducting samples of type Tl2Ba2Ca 2Cu3-xFexO10-δ; with 0 x 0.4, have been prepared using a single step of solid-state reaction. The prepared samples have been characterized using X-ray powder diffraction (XRD), ...
