ABSTRACT:
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.
