High-T_c Superconducting Electronics: Implications of Reduced Dimensionality

Abstract

First, we present experimental evidence that Bi-Sr-Ca-Cu-O superconductors are effectively quasi-two dimensional, in both the normal and the superconducting state. Next, we analyze how this unusual property of the material influences the quest for active electronic components based on high-T_c superconductors, with focus on trilayer Josephson junctions and ferroelectric/superconductor field-effect devices.
