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.
