MAGNETOPLASMA OSCILLATIONS OF A TWO-DIMENSIONAL, TWO-COMPONENT PLASMA

Abstract

We investigate the magnetoplasma excitations in a system comprised of two parallel two-dimensional conducting layers separated by a distance 2d>0. The individual layers are assumed to have, in general, different effective masses, particle densities and charges. The dispersion equations are derived quantum mechanically within the random phase approximation and the spectrum of the long wavelength collective modes is calculated. We also investigate the mutual phase of two-dimensional magnetoplasma oscillations and show that this mutual phase is similar to that in the three-dimensional case and does not depend on the interlayer distance.
