Fabrication of interface elements for oxide RSFQ circuits

Y. Tarutani, Yoshihiro Ishimaru, H. Wakana, Masahiro Horibe et autres

RSFQ circuit elements were fabricated based on the YBa/sub 2/Cu/sub 3/O/sub 7-x/ ramp-edge junctions and their characteristics were investigated. In particular, two types of interface circuits were designed, fabricated and their amplification functions were evaluated. The interface circuits comprised series array of …

Study of Si-coupled superconducting field-effect transistor by tunneling spectroscopy

T. Nishino, Mutsuko Hatano, H. Hasegawa, T. Kure et autres

A superconducting field-effect transistor with a 0.1- mu m length gate electrode was fabricated, and its performance was studied by tunneling spectroscopy. Two superconducting electrodes (source and drain) were formed by a self-aligned fabrication process. Superconducting current flowing through the semiconductor (Si) …
