spin light-emitting diode (LED)spintronicsGaAs-based spin LEDs were used to study spin injection through a Schottky barrier from a ferromagnetic contact formed by an in-situ technique. Optical measurements were performed in both oblique Hanle and Faraday geometry. In addition to direct recombination ...

The device used in this case is a GaAs/AlGaAs light-emitting diode, and spin polarization is confirmed by the circular polarization state of the emitted light.doi:10.1038/45502R. FiederlingM. KeimG. ReuscherW. OssauG. SchmidtA. Waag
Photons are emitted from an electrically operated spin light-emitting diode consisting of the diluted magnetic semiconductor ZnMnSe and an InGaAs quantum dot as single photon source. The circular polarization degree of the emitted light is high (96 % at 6 T). Autocorrelation traces recorded with ...

A spin light-emitting diode (LED), depicted in Figure 3, can be viewed as a prototypical detector of spin polarization. Similar to a an ordinary LED (Sze, 1981), electrons and holes recombine (in a quantum-well (QW) or a p–n junction) and produce EL or PL. However, in a spin ...
We then describe our recent development of the coupled-cluster equation of motion method and present its application to the theoretical study of singlet and triplet exciton formation rates and polymer light-emitting diode quantum efficiency. It is found that, in general, singlet excitons can be ...
light-emitting diodes, their performance is limited by non-radiative pathways introduced in electroluminescence. Here we present a host–guest design for organic light-emitting diodes that exploits energy transfer with up to 9.6% external quantum efficiency for 800 nm emission. The tris(2,4,6-...
