DUAL ELECTRODE TYPE SPIN LIGHT-EMITTING DIODE AND LASER

摘要

PROBLEM TO BE SOLVED: To easily switch over circular polarization and make the change faster considering the problem that the conventional diodes have.SOLUTION: The dual electrode type spin light-emitting diode includes a pair of magnetic metal electrodes whose directions of magnetization are mutually anti-parallel formed on an upper surface of a barrier layer of a spin light-emitting diode having a light-emitting double heterostructure.
