Unusual crystal structure of non-superconducting Y1Ba2Cu3O7−x films on buffered silicon substrates

Photocatalytically Active YBa2Cu3O7−x Nanoparticles Synthesized via a Soft Chemical Route

“…The distortion of Cu-O crystal plane caused by a certain amount of oxygen deficiency plays a significant role in superconductivity [23]. However, in some structure modified cases, the normal crystal structure related to superconductivity may be changed, resulting in nonsuperconductivity of YBCO materials (which may eventually transform to the semiconductor) [24,25]. It is known that the fixed band gap in a semiconductor is the origin of its photocatalysis.…”

“…In the deposition on conventional Si substrates the thickness of the film is limited to ∼ 50 nm in. Thicker films exhibit cracks and show degraded superconducting characteristics [131,132]. When SOI wafers are used the strain is relaxed to the SiO 2 interlayer [133] and YBCO film thicknesses of over ∼400 nm can be realized [105].…”
