Superconducting Electronics: Science and Technology Update
There have been several recent developments, both in the science and technology, of superconducting electronics. On the technology front, HTS RF components have been integrated with cryogenic low noise semiconductor amplifiers and very small cryocoolers to build very high sensitivity and selectivity, wireless communication receivers and radar for a host of military and commercial applications. On the science front, superconducting materials are being integrated with magnetic materials to explore the effects of spin polarized current injection on the properties of various device structures. Andreev scattering at a superconductor to metal contact is being used to determine the extent to which the electrons at the Fermi surface of a metal are spin polarized.
