Quantum Tunnelling - overview
Physics Accomplishment | 1958
IBM researcher: Leo Esaki
Where the work was done: IBM T.J. Watson Research Center
What we accomplished: Leo Esaki's discovery of the semiconductor junction, called the Esaki diode, finds wide use in electronics applications. More importantly, his work in the field of semiconductors lays a foundation for further exploration in the electronic transport of solids. Leo Esaki (pictured) won the 1973 Nobel Prize in Physics for his work in Quantum (or Electronic) Tunnelling.
