...It would be valuable to perform realistic calculations of a spinpolarized transport and spin injection which would treat the whole spin LED as a single entity....
[...]
...However, in a spin LED, as a consequence of radiative recombination of spin-polarized carriers, the emitted light is circularly polarized....
[...]
...(III,Mn)V ferromagnetic semiconductors are also used to inject spin in spin-LED structures as depicted in Fig....
[...]
...Both results clearly demonstrated a robust low-temperature spin injection using spin LED’s....
[...]
...Spin injection can be achieved even with no external field, and the reports of high TC in some compounds suggest that all-semiconductor spin LED’s could operate at room temperature....
