Abstract:

Circularly polarized electroluminescence from light-emitting diodes based on InGaAs/GaAs heterostructures with adjacent ferromagnetic delta-doped layer has been investigated. It was found that delta-layer placed near (at 2-10 nm) the quantum well (QW) causes circular polarization of its electroluminescence due to an s,p-d exchange interaction between holes in the quantum well and Mn ions in the delta-layer. The dependence of circular polarization degree on main technology parameters is discussed.
