Magnetoplasma Resonance in the Dynamic Conductivity of a Type I Superlattice
We have examined the effect of a magnetic field on the strong plasma resonance of the dynamic conductivity of a close-packed Type I superlattice using a magneto-hydrodynamic analysis of the superlattice memory function. We have determined explicitly the finite jump in the imaginary part of the memory function characterizing a plasma resonance shifted by the magnetic field to the magneto-plasmon frequency (ωp 2+ωc 2)1/2 where ωc is the cyclotron frequency and ωp = (4πe2n2D/md)1/2 is the bulk plasmon frequency for a closely packed Type I superlattice of period d and 2D electron sheet density n2D.
