The influence of the local crystallographic orientation of the polycrystalline bottom platinum electrode on the crystallization of niobium pentoxide thin films during their rapid thermal annealing was investigated by X-ray diffraction, X-ray reflectivity and transmission electron microscopy. The Nb2O5thin films under study were reactively sputtered in a mixed O2/Ar atmosphere and subsequently subjected to the annealing in argon atmosphere at temperatures ranging from 500∘C to 700∘C. The X-ray diffraction confirmed a transition from the amorphous niobium oxide to the crystalline orthorhombic Nb2O5for temperatures between 500∘C and 600∘C. The X-ray reflectivity measurements showed that the crystallization process was accompanied by a continuous increase of the electron density in Nb2O5and by a rapid increase of the surface roughness at 700∘C. It was further observed by transmission electron microscopy that Nb2O5crystallizes selectively and that the crystalline domains of Nb2O5possess a strong orientation relationship to the platinum from the bottom electrode. The orientation relationshipwas identified as the most beneficial one for crystallization of Nb2O5.
