Spin transistor
The spin transistor , abbreviated to spin FET , is a group of special field effect transistors (FET) which use the quantum mechanical property of the spin of electrons in the context of the Rashba effect . Conventional field effect transistors, which are components of electronics , only use the electrical charge to store information and to amplify electrical signals.
Spin transistors are assigned to spintronics , a branch of nanotechnology , and are used in existing applications for non-volatile information storage in special memories such as magnetoresistive random access memory (MRAM).
First work on spin transistors took place in the 1990s at Bell Laboratories . Spin transistors are part of various research projects in the basic sector of semiconductor technology , but have so far not been able to establish themselves in economically important applications.
