Laser ablation of BiSrCaCuO superconducting thin film: analysis of intermediate species in real time

The presence of oxygen during the ablation process of BiSrCaCuO leads to gas-phase production of oxides and might affect the growth and crystallinity of the thin films. It is very probable that ground-state and excited oxides are formed in the plume. Reactive scattering of O2 on Sr atoms producing SrO in an excited state is observed in emission spectroscopy (OMA III). XRD analysis of the behavior of the FWHM of 0010 and 0012 reflection lines is reported, as well as the SEM and EDS analysis of superconducting films.
