Single intrinsic Josephson junction with double-sidedfabrication technique
We make stacks of intrinsic Josephson junctions (IJJs) embedded in the bulk of very thin ( d ⩽ 100 nm ) Bi 2 Sr 2 Ca Cu 2 O 8 + x single crystals. By precisely controlling the etching depth during the double-sided fabrication process, the stacks can be reproducibly tailor-made to be of any microscop...

, i.e., enclosing a specified number of IJJ (0-6), including the important case of a single junction. We discuss reproducible gaplike features in the current-voltage characteristics of the samples at high bias. |
