Magnetoplasma excitations of nonuniform 2D electron systems in a strong magnetic field
Mikhailov S. A.
The spectrum of magnetoplasmons propagating along a contact between two 2D layers in a strong magnetic field is calculated. It is assumed that the electron density near the interface varies smoothly over a macroscopic distance. It is also assumed that a complex structure of alternating bands of compressible and incompressible fluids can form in quantizing magnetic fields at low temperatures. It is shown that this structure can be studied through spectroscopy of inter-edge magnetoplasmons. © 1995 American Institute of Physics.
