Ion implantation and mass transport in YBa2Cu3O7−δ films and substrates

Determination of Ca diffusion in YBCO films by Secondary Ion Mass Spectroscopy

“…However, it was supposed that the Ca diffusion along the grain boundaries was responsible for the appearance of diffusion tails. Similarly, Kilner and Li [33] reported that short-circuit paths in YBCO played an important role in oxygen diffusion in YBCO thin films.…”

Developing a trilayer processing technique for superconducting Y Ba2Cu3O7−δthin films by using Ge ion implantation

“…For the multilayer device fabrication in semiconductor technology, ion implantation has commonly been in use for last few decades. In high temperature superconducting materials, the ion implantation technique has been used for modifying the structure and improving some critical parameters of superconductors with various types of ions [10][11][12][13][14][15][16][17][18][19][20]. The idea of using the ion implantation technique with suitable ion energy and dose for the purpose of creating an insulating layer serving as a separator between the superconducting layers was the main motive of this work.…”

Electrical and magnetic properties of Si ion implanted YBa2Cu3O7−δ thin films and microbridges

“…In high temperature superconducting materials, ion implantation technique has been employed for the processing of oxide thin films suitable for the fabrication of superconducting devices [5]. The improvement in the current density and crystallinity of YBCO with O + ion implantation was studied by Non et al [6], Lia et al has studied the superconductivity of YBCO via C + implantation [7], patterning of YBCO thin films by O + ion implantation was studied by Kuhn et al [8], the study of ion implantation and mass transport in YBCO were made by Kilner et al [9]. In ion implantation, accelerated ions create point defects, which cause significant changes in superconducting properties of YBCO layers depending on the dose of the implanted ion and energy.…”
