Prof. Dr. Brian David Josephson > CV
According to quantum physics electrons behave both like particles and like waves, which can penetrate barriers that would obstruct its passage if the electron worked as a particle in the classical way.
This property is known as ‘tunnelling’.
Brian Josephson received one of the two 1973 physics prizes for his theoretical predictions of properties in a superconducting current flowing through a tunnel barrier.

Ivar Giaever (USA) and Leo Esaki (Japan) shared the other prize for their experimental discoveries regarding tunnelling phenomena in superconductors and semiconductors respectively.
In 1960 Giaever at General Electric in the US demonstrated the tunnel effect through a very thin layer of oxide surrounded by metal in a superconducting or normal state.
This experiment inspired Brian Josephson — then a graduate student at Cambridge — to analyse the tunnelling theory, which led him in 1962 to predict new phenomena in superconductors. Generally
