This invention pertains to a spintronic device for emitting light and to a method
for its operation. The device includes a cathode electrode capable of producing
spin-polarized charge carrier electrons under the influence of an electric field;
an anode electrode spaced from the cathode for producing spin-polarized charge
carrier holes; an intermediate medium disposed between the electrodes into which
the carriers are injected under the influence of an electric field and which serves
as a transport medium for the carriers wherein the carriers are transported and
within which the carriers react and form excitons; and a circuit between the electrodes
for imparting en electric field which serves as the motive force for the carriers.
The method includes the steps of producing spin-polarized electrons, producing
spin-polarized holes, passing the electrons and the holes through a transport medium
under influence of an electric field whereby the electrons and the holes, being
oppositely charged, combine to produce excitons which produce light, and collecting
the light so produced.
