Silicon-based spintronics

[Wien Ee]

In a development that may pave the way for new types of microelectronic devices, researchers have demonstrated that electron spin can be transported and manipulated in silicon.

Das toch wel cool zo'n spin filter, ben benieuwd of, en voor wat voor applicaties het gebruikt kan worden:

The device features a novel design that consists of an electron emitter and a silicon film that is sandwiched between a pair of ferromagnetic materials, Co84Fe16 and Ni80Fe20, which serve as spin filters that can be activated independently.


As electrons impinge upon the CoFe material, only one orientation of spin passes through to the silicon film. Electrons with the opposite spin are blocked.

Je hebt nog wel magnetische materialen nodig zoals cobalt, nickel en ijzer. in de quote hierboven betekend Co84Fe16 een laagje van 84% Cobalt en 16% ijzer (niks met atoomnummer te maken ofzo)
