“…But in any event, at their high dose extremes, the knock-out effect may not be negligible anymore and its impact on the T C and normal state resistivity could hence have overshadowed the concurrent ordering effect. Meanwhile, it is worth noting, our Raman results were reproducible over long time room temperature ageing, though it is not clear as to why our sample demonstrated 8 this extra resilience in comparison with earlier reports [1][2][3][4]26], considering the commonly accepted high mobility of chain oxygen atoms.…”

Critical temperature depression and persistent photoconductivity in ion irradiated YBa2Cu3O7−x films and YBa2Cu3O7−x/PrBa2Cu3O7 superlattices

“…All models for persistent photoconductivity in high temperature superconductors are based on the presence of disorder in the chain structure: charge transfer models, 8,9 electron trapping in oxygen vacancies, [10][11][12] and photoassisted oxygen ordering. 13 We may expect, therefore, persistent photoconductivity on irradiated YBCO films much in the same way as in oxygen deficient films. In this line Figs.…”

“…Since the very first years after the discovery of high T c superconductors (HTSC), it has been well known that irradiating oxygen-deficient YBa 2 Cu 3 O 6+x (YBCO) thin films with visible light induces persistent photoconductivity (PPC) as well as persistent photoinduced superconductivity (PPS) [1,2].…”
