Interference of Magnetic-Dipole and Electric-Dipole Interactions in Semiconductors
並列摘要
We have shown that the anomalous dependence of spin-resonance intensity on the sign of either the dc magnetic field B0 or the wave vector q of the photon observed in InSb can be understood by the interference between electric-dipole and magnetic-dipole interactions when the former become allowed by virtue of mixing of Landau and Zeeman levels by a spin-orbit interaction lacking inversion symmetry. A theoretical study of this phenomenon in semiconductors with zinc-blende structure is presented for the principle experimental configurations. This effect provides an elegant way to obtain the parameter which causes the electric-dipole-induced spin resonance. We also investigate the electric-dipole and magnetic-dipole interference in semi-conductor with wurtzite structure.
