Abstract
The present invention relates to a method and a device for providing a current of spin-polarised electrons. More particularly, the present invention is suited for use in spin electronics or detection of spin-polarised electrons.
Claims16
A spin filter device, the device comprising:
- a substrate;
- and
- at least one monolayer deposited upon said substrate,
- wherein said monolayer comprises asymmetrical molecules, and is adapted to filter electrons travelling from said substrate through said at least one monolayer such that electrons that exhibit a predetermined spin can pass.

Use of a spin filter device for generating a current having a first substrate and at least one monolayer deposited on the first substrate, with the following steps of
- (a) producing a current of electrons from the first substrate to travel into the at least one monolayer;
- and
- (b) injecting electrons which have passed the at least one monolayer into a second substrate;
- wherein the at least one monolayer comprises asymmetrical molecules adapted to filter the current of electrons such that electrons that exhibit a predetermined spin can pass to generate a current of spin-polarised electrons.
