“…However, films made by PLD are usually characterized by coarse grain structure and a particulate population consisting of outgrowths, droplets and often debris from the target. Comparative studies on PLD film growth, reported by several groups [5,6,[10][11][12][13], show that superior quality films, in terms of smoothness, crystallinity and stability, can be made with NBCO compared with YBCO. The optimization of the deposition depends on a complex interplay between many parameters, but the most important parameter, common to all the studies reported, appear to be the substrate temperature, the laser fluence on the target, the target composition and density, the substrate lattice parameter and surface morphology and the ambient oxygen pressure.…”
