Andreev reflection

Quick Reference

A process occurring at the interface between a normal conductor of electricity and a superconductor, in which charge is transferred from the normal conductor to the superconductor. This results in the formation of a Cooper pair in the superconductor and a reflected hole in the normal conductor. The process was first described by the Russian physicist Alexander Andreev in 1964. It has possible applications in spintronics and quantum computing.
