Coulombic effects on magnetoconductivity oscillations induced by microwave excitation in multisubband two-dimensional electron systems
We develop a theory of magneto–oscillations in photoconductivity of multisubband two-dimensional electron systems which takes into account strong Coulomb interaction between electrons. In the presence of a magnetic field oriented perpendicular, internal electric fields of fluctuational origin caus...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We develop a theory of magneto–oscillations in photoconductivity of multisubband two-dimensional electron
systems which takes into account strong Coulomb interaction between electrons. In the presence of a magnetic
field oriented perpendicular, internal electric fields of fluctuational origin cause fast drift velocities of electron
orbit centers which affect probabilities of inter-subband scattering and the photoconductivity. For the electron
system formed on the liquid helium surface, internal forces are shown to suppress the amplitude of magnetooscillations,
and change positions of magnetoconductivity minima which evolve in zero-resistance states for high
radiation power.
