History of the Josephson effect

{c}
{tag=Physical Review Letters}
{title2=1963}
{title2=Observation of the Josephson effect}

Paper by <Philip W. Anderson> and <John M. Rowell> that first (?) experimentally observed the <Josephson effect>.

<Closed access academic journals are evil>[Paywalled] by the <American Physical Society> as of 2023 at: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.10.230

<DOI>: https://doi.org/10.1103/PhysRevLett.10.230

TODO understand the graphs in detail.

They used <tin>-oxide-<lead> tunnel at 1.5 K. TODO oxide of what? Why two different metals? They say that both films are 200 nm thick, so maybe it is:
``
   -----+------+------+-----
...  Sn | SnO2 | PbO2 | Pb  ...
   -----+------+------------
          100nm 100nm
``

A reconstruction of their circuit in <Ciro's ASCII art circuit diagram notation> TODO:
``
DC---R_10---X---G
``

There are not details of the physical construction of course. <Reproducibility> lol.
