英文摘要a spin-injection/-detection device has been fabricated based on the multiple quantum well light emitting diode (led) structure. it is found that only a broad electroluminescence (el) peak of a full width at half maximum of 8.6 nm appears at the wavelength of 801 nm in el spectra with a circular luminescence polarization degree of 18%, despite pl spectra always show three well resolved peaks. the kinetic energy gained by injected electrons and holes in their drift along opposite directions broadens the el peak, and makes three el peaks converge together. the same process also destroys the injected spin polarization of electrons mainly dominated by the bir-aronov-pikus spin relaxing mechanism.; A spin-injection/-detection device has been fabricated based on the multiple quantum well light emitting diode (LED) structure.
