Mechanical and decorative properties of ZrOx thin films
Within the frame of this work is zirconium oxide - ZrOx decorative thin films were deposited by reactive magnetron sputtering. These films have been characterized in terms of some proprieties as films colour, mechanical properties, thickness and composition, taking into account the influence of certain deposition parameters such as: reactive gas flow (O2) and deposition time. Regarding the composition, the obtained films are characterized by two

Epitaxial Bi:2201 thin films were deposited on SrTiO3 (100) substrate using the DC magnetron sputtering method. Optimal deposition conditions for superconducting films with smooth film surface and high epitaxial quality were obtained. The effect of partial oxygen pressure (fO2) in sputtering gas on the electrical resistivity was studied. The phase diagram for transition temperature and localization temperature function of oxygen partial pressure
Read moreGreen’s Conjecture for curves on arbitrary K3 surfaces
Green’s conjecture predicts than one can read off special linear series on an algebraic curve, by looking at the syzygies of its canonical embedding. We extend Voisin’s results on syzygies of K3 sections, to the case of K3 surfaces with arbitrary Picard lattice. This, coupled with results of Voisin and Hirschowitz–Ramanan, provides a complete solution to Green’s conjecture for smooth curves on arbitrary K3 surfaces.
