Abstract

We report the properties of a spin-polarized In0.4Ga0.6As/GaAs quantum-dot surface-light-emitting diode with a Ga0.974Mn0.026As spin injector layer. Spin-polarized holes from this ferromagnetic layer recombine with electrons in the quantum dots to produce circularly polarized light output. The peak optical polarization efficiency at 5.1 K is 18% and the spin injection efficiency is estimated to be ∼36%. The temperature dependence of spin injection is almost identical to the temperature dependence of magnetization in the (Ga, Mn)As layer.
