Novel in-situ fabricated Josephson Junctions: tyrilayer on a substrate slope
Mid Sweden University, Faculty of Science, Technology and Media, Department of Engineering, Physics and Mathematics.
2003 (English)In: IEEE TRANSACTIONS ON APPLIED SUPERCONDUCTIVITY ASC, ISSN 1051-8223, Vol. 13, no 2, part 1, 794-796 p.Article in journal (Refereed) Published
Abstract [en]

We demonstrate a high-temperature superconductor (HTS) Josephson junction geometry using only in situ interfaces and with the current flowing in the – plane of the HTS. The trilayer on a substrate slope (TOSS) junction is a HTS-barrier-HTS structure deposited in situ on top of a pre-etched slope in the substrate. We present initial results on the fabrication and testing of YBa2Cu3O7 TOSS junctions with a Ga-doped PrBa2Cu3O7 barrier. These devices display resistively shunted junction like – characteristics with characteristic voltages up to 5 mV at 4.2 K. The TOSS junction concept is of interest for fundamental studies of interfaces in HTS and can also be applied to an integrated circuit technology.
