Bruno, F. Y. ; Tornos, J. ; Gutierrez del Olmo, M. ; Sánchez Santolino, G. ; Nemes, N.M. ; Gárcia Hernández, M. ; Méndez Martín, Bianchi ; Piqueras de Noriega, Javier ; Antorrena, G. ; Morellon, L. ; De Teresa, J. M. ; Clement, M. ; Iborra, E. ; León, C. ; Santamaría Sánchez-Barriga, Jacobo | American Physical Society | 2011-06-23Metallic surface layers are fabricated by doping (100) SrTiO_3 (STO) single crystals with oxygen vacancies generated by bombardment with Ar ions from an rf plasma source. The presence of oxygen vacancies is confirmed by cathodoluminescence and x[...]texto impreso
Sefrioui, Zouhair ; Arias, D. ; González Herrera, Elvira María ; León, C. ; Santamaría Sánchez-Barriga, Jacobo ; Vicent López, José Luis | American Physical Society | 2001-02-01Epitaxial YBa_2Cu_3O_7 thin films, grown by high-pressure de sputtering, an irradiated with He^(+) ions at 80 keV with doses between 10_(14) and 10_(15) cm^(-2). Irradiation reduces the critical temperature but it does not modify the carrier con[...]texto impreso
Sefrioui, Z. ; Arias, D. ; León, C. ; Santamaría Sánchez-Barriga, Jacobo ; González Herrera, Elvira María ; Vicent López, José Luis | American Physical Society | 2004-08We investigate the zero-magnetic-field dynamic scaling in Bi_2Sr_2CaCu_2O_8 thin films from nonlinear current-voltage (I-V) characteristics and by using the concavity criterion recently proposed by Strachan [Phys. Rev. Lett. 87, 067007 (2001)] .[...]
