Deposition of LiNbO₃ thin films on c-axis oriented epitaxial Y₁Ba₂Cu₃0_7-δfilms by pulsed excimer laser ablation

Abstract

Pulsed excimer laser ablation technique has been used to deposit thin films of LiNbO₃ on epitaxial c-axis oriented Y₁Ba₂Cu₃0_7-δ films grown on (100) SrTiO₃ substrates. Initial parameter optimization studies for achieving the desired stoichiometry have been performed by depositing the LiNbO₃ films on (100) Si substrates and the corresponding results have been used as guidelines for realization of high quality films on the Y₁Ba₂Cu₃0_7-δ surface. These films are examined by using X-ray diffraction technique.
