Title: Superconducting epitaxial YBa 2Cu 3O 7-δ on SrTiO 3 buffered Si (001)

Abstract

Thin films of optimally-doped (001)-oriented YBa 2Cu 3O 7-δ are epitaxially integrated on silicon (001) through growth on a single crystalline SrTiO 3 buffer. The former is grown using pulsed-laser deposition and the latter is grown on Si using oxide molecular beam epitaxy. The single crystal nature of the SrTiO 3 buffer enables high quality YBa 2Cu 3O 7-δ films exhibiting high transition temperatures to be integrated on Si. For a 30 nm thick SrTiO 3 buffer, 50 nm thick YBa 2Cu 3O 7-δ films that exhibit a transition temperature of ~ 93 K, and a narrow transition width (< 5 K) are achieved. Furthermore, the integration of single crystalline YBa 2Cu 3O 7-δ on Si (001) paves the way for the potential exploration of cuprate materials in a variety of applications.
