Dual mode cross slotted filter realized with double-sided Tl2Ba2CaCu2O8 films grown by MOCVD

bstract We report on the realization of dual mode microwave filters based on Tl2Ba2Ca1Cu2O8 (Tl-2212) double-sided superconducting films. The Tl-2212 samples have been grown ex situ on 10× 10 mm2 LaAlO3 (100) substrates by a combined approach of metal-organic chemical vapour deposition (MOCVD) and thallium vapour diffusion. Their morphological, compositional and structural natures have been investigated by scanning electron microscopy, energy dispersive x-ray analyses and x-ray diffraction ...
