摘要: Metallization of high-Tc superconductors using low resistivity metal oxides and Cu-Ge alloys has been investigated on high quality pulsed laser deposited epitaxial YBa2Cu3O7-x (YBCO) films. Epitaxial LaNiO3 (LNO) thin films have grown YBCO at 700°C deposition. The specific LNO was measured to be 50 µΩ-cm 300K which decreases 19 100K indicating good metallicity the contact resistance LNO-YBCO film interface found reasonably (of order 10-4Ω-cm2 77K) suggests that formed between two is quite clean can emerge as a promising electrode-material A preliminary investigation related compatibility Cu3Ge alloy metallization material discussed. usage other oxide based materials such SrRuO3 (SRO) SrVO3 (SVO) for superconductor also
