Strain-induced structural changes in thin YBa2Cu3O7−x films on SrTiO3 substrates

Post Deposition Heat Treatment Effects on Ceramic Superconducting Films Produced by Infrared Nd:YAG Pulsed Laser Deposition

“…The value of c-lattice parameters for film not subjected to oxygen annealing is about c= 11.77 while for oxygen annealed film, c= 11.68 . The value of the c-lattice for oxygen annealed film is similar to the oxygen rich Y-123 (c= 11.68 ) [30] . The variation in c-lattice can be attributed to the decrease in the fraction of oxygen gas in YBCO material [25].…”

Characterization of the insulator barrier and the superconducting transition temperature in GdBa2Cu3O7−δ/BaTiO3 bilayers for application in tunnel junctions

“…First, the T s in the bottom electrode could be strongly affected by stress, and the tetragonal distortion, induced by the BTO. 23 The effect could be more relevant for thick BTO insulating layers. Second, as observed from CAFM measurements, the density of pinholes is strongly reduced when the BTO thickness is increased.…”

“…The T s of the bilayers is systematically suppressed by increasing the BTO thickness, which can be associated with reduced orthorhombicity in the GBCO electrode by changes in the oxygen stoichiometry. [23][24][25]…”

From nanowires to cubes of CdO: Ethanol gas response

“…It is found that all surfaces are hydrophilic in nature as water Contact angle is less than 90 • . Contact angle is found to be decreased with increase in film thickness due to improvement in roughness and network-like architecture, which creates air crevices in-between the wires and also the thick film has relatively less internal and external strain energies compared to the thin one [18]. Variation in thickness, surface roughness and hence in contact angle with thickness is given in Table 1.…”
