Abstract:

The Spin-Dicke effect is a phenomenon already observed in electrically detected magnetic resonance (EDMR) of organic devices. The EDMR effect involves changing electron spin-states to control a recombination current. In the Spin-Dicke phenomenon, the oscillating field, B1, which causes resonance and changing spin-states, is approximately equal to the quasi-static magnetic field, B0. In these experiments, the EDMR effect under the Spin-Dicke regime was observed in inorganic semiconductor devices (SiC p-n junctions) via spin-dependent recombination.
