Spinristor – a Swiss army knife of molecular electronics

A new study presents in silico proof of concept of a new type of molecular electronic component that combines functionalities of a spin-filter, molecular switch, and a diode in a single molecule, called a spinristor. 

Spinristor, described by the team led by Michal Straka of IOCB Prague and Cina Foroutan-Nejad of IOCB Prague and IOC PAS, consists of a single molecule of Ti@C70 connected to electrodes in an electric circuit. With a low voltage applied, the Ti@C70 molecule rectifies the current and filters the electrons according to their spin. A higher voltage at Ti@C70 causes relocation of the titanium atom, thus switching the whole system into different rectification and spin-filtering characteristics.

Such functionality could bring new applications in the future computers' architecture, in particular in-memory computing, and in spintronics.

The proposed device doesn’t seem to have an equivalent in macroscopic or molecular electronics so far.
