Probable observation of the Josephson superconducting tunneling effect by Ciro Santilli 34 Updated 2024-11-19 Created 1970-01-01
Paper by Philip W. Anderson and John M. Rowell that first (?) experimentally observed the Josephson effect.
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.
