Andreev reflection, named after the Russian physicist Alexander F. Andreev, is a type of particle scattering which occurs at interfaces between a superconductor (S) and a normal state material (N). It is a charge-transfer process by which normal current in N is converted to supercurrent in S.
Alexander Fyodorovich Andreev (Russian: Александр Фёдорович Андреев, 10 December 1939 – 14 March 2023) [1] was a Russian theoretical physicist best known for explaining the eponymous Andreev reflection. [2] Andreev was educated at the Moscow Institute of Physics and Technology, starting in 1959 and graduating ahead of ...
The table below shows some of the parameters of common superconductors.X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla.

Plot showing superconducting electron density versus depth in normal and superconducting layers with two coherence lengths, and .. Proximity effect or Holm–Meissner effect is a term used in the field of superconductivity to describe phenomena that occur when a superconductor (S) is placed in contact with a "normal" (N) non-superconductor.

Assume that superconductor A has Ginzburg–Landau order parameter =, and superconductor B =, which can be interpreted as the wave functions of Cooper pairs in the two superconductors. If the electric potential difference across the junction is V {\displaystyle V} , then the energy difference between the two superconductors is 2 e V ...
