Although a variety of buffer layers have been routinely reported, a standard architecture commonly used for the Y Ba2Cu3O7−x (YBCO) coated conductor is Y BCO/CeO2/Y SZ/CeO2/substrate or Y BCO/CeO2/Y SZ/Y2O3/substrate where ceria is typically the ca

Epitaxial growth of YBa 2 Cu 3 O 7− x (YBCO) layers on TiN(0 0 1) surfaces was explored, both with and without CeO 2 intermediate layers. The epitaxial TiN layers were grown on MgO(0 0 1) and textured Ni substrates. Thin CeO 2 (∼200 nm thick) and

Ag-doped YBa 2 Cu 3 O 7− x films, with thickness ranging from 0.06 to 2.5 μ m, were deposited by pulsed laser ablation onto (100) LaAlO 3 single-crystal substrates. The target was YBa 2 Cu 3 O 7− x with 5 wt.% Ag addition. The presence of Ag in

XPS studies of a typical YBCO coated conductor architecture were conducted to investigate the chemical and microstructural profiles. The detailed XPS depth profiling study was performed on one sample (YBCO/CeO2/YSZ/CeO2/Ni) of coated conductor. The c

Pulsed laser deposition of Yba2Cu3O7-δ?(YBCO) coated conductors was studied for the range of P(O2) from 120 mTorr to 1200 mTorr, higher than typically used oxygen partial pressures during deposition. The purpose of the investigation was to determine

A low power AO Q-switched Nd:YAG laser operating at 1064 nm has been used to texture the surface of metallic substrates such as nickel, hastelloy, and aluminum. The substrate surface is uniformly exposed to the laser by using a scan head to raster th
