Properties of Josephson Junction Fabricated on Bicrystal Substrate with Different Misorientation Angles
In order to develop YBa 2 Cu 3 O 7-δ bicrystal junctions suitable for high-performance superconducting quantum interference device (SQUID), the relationship between the junction properties and the misorientation angle of the bicrystal substrate is studied experimentally. Misorientation angles of 24°...

bicrystal junctions suitable for
high-performance superconducting quantum interference device (SQUID), the relationship
between the junction properties and the misorientation angle of the bicrystal substrate
is studied experimentally. Misorientation angles of 24°, 27°, 30°, 33° and 36.8° are used,
and the angular dependencies of junction resistance

investigated. It is shown that values of

=const. in these junctions. The obtained results are analyzed in terms of the
direct and resonant tunneling mechanisms. It is also shown that values of

≈10 Ω
and
I

≈20 µA can be obtained rather reproducibly when we use the 30° junctions. The
properties of this junction are very promising for the development of
high-performance SQUID. |
