Stacks of intrinsic Josephson junctions singled out from inside Bi2Sr2CaCu2O8+x single crystals

Using a double-side fabrication method, a stack of intrinsic Josephson junctions plus a bow-tie antenna and chokes were made in a slice 200 nm thick and singled out from inside a bulk Bi2Sr2CaCu2O8+x single crystal. The junctions in the fabricated stack were very uniform, and the number of junctions involved was rather controllable. Potentially it would be possible to use this method to fabricate integrated circuits based on intrinsic Josephson junctions in high T-C superconductors. (C) 2001 American Institute of Physics.
