Abstract:

We report the systematic substitution of Nb at the Cu1 site of YBa2Cu2NbOy in thin films to form a new phase of YBa2Cu2NbO8. These films were deposited on SrTiO3100 crystals using pulsed laser deposition and deposited at an optimal temperature of 850 degrees C. Films were characterized using x-ray diffraction XRD, atomic force microscopy, x-ray photoelectron spectroscopy XPS, micro-Raman spectroscopy, and transmission electron microscopy. XRD of these films indicate c-axis oriented YBa2Cu2NbOy formation. XPS and micro-Raman spectroscopy analysis suggests Cu exists in the 2 state.
