A junctionless light emitting device comprises a field emitter cathode, and a light emitting semi-conductor material sandwiched between an ohmic contact (OC) that faces the injected electrons and a Schottky contact (SC). The field emitter cathode is configured to inject electrons into the ohmic contact.
