Abstract

Physics - Superconductivity

Journal of Applied Physics 102, 113720 (2007) Transport in electronic devices based on high-Tc superconductors depends critically on the charge redistribution at interfaces, since the band structure is modified on a local scale. Using the density functional theory approach for relaxed YBa2Cu3O7-metal contacts, the charge transfer into the superconductor has been studied in Appl. Phys. Lett. 90, 192502 (2007). In the present paper we discuss the systematics inherent in the local electronic structure of the near-contact YBa2Cu3O7 sites, in particular the dependence on the contact geometry.
