Spectroscopic method for determining the size of the Coulomb gap in the energy spectrum of an incompressible Fermi liquid of 2D electrons
Kukushkin I. V., Timofeev V. B.
An anomalous behavior has been observed for the spectral position of an emission line during the condensation of a gas of 2D electrons into an incompressible Fermi liquid. A spectroscopic method is proposed for an independent determination of the energy gaps in the spectrum of excitations: quasielectrons and quasiholes.
