LaNiO3 is a metallic perovskite with suitable electric properties to be used as an conductive electrode in an all oxide hetero-structure. The fabrication of a such material on a SrTiO3 (100) substrate by pulsed laser deposition has been studied in function of the oxygen partial pressure and substrate temperature. The variation of these two growth parameters results in changes in structure, morphology, optical and electrical properties of the thin films. An epitaxial growth has been obtained for an optimal set of parameters. High temperature in-situ spectroscopic ellipsometry (SE) was used to study the growth and the thermal variation of the optical properties in the temperature range of 300K to 1070K.
