Abstract :
Attempts to develop high temperature superconductor (HTS) microelectronics have been limited by the immature nature of HTS circuit technology. Much of the present effort worldwide is based on superconductor-normal-superconductor (SNS) Josephson junctions (JJ´s). Only within the past three years have SNS junctions been fabricated which can be interpreted with conventional proximity effect theory. We discuss the history and present status of HTS SNS devices and the prospects for producing a mature technology for practical applications.
