Effective mass of a space-charge layer on GaAs in a parallel magnetic field.
01 January 1986
The effective mass of a quasi two-dimensional electron space- charge layer on GaAs has been studied in a plasmon resonance experiment for magnetic fields applied in the plane of the layer. An anisotropy of the effective mass induced by the parallel magnetic field is observed. For the in-plane direction perpendicular to the magnetic field the mass increases with its reciprocal depending quadratically on the magnetic field strength.
