Direct determination of the state density of 2D electrons in a transverse magnetic field
Kukushkin I. V., Timofeev V. B.
The energy distribution of the state density of 2D electrons in a quantizing transverse magnetic field is determined from the radiative-recombination spectra of 2D electrons as they recombine with injected holes in Si (100) metal-insulator-semiconductor structures. Oscillations are observed in the width of the Landau levels as a function of the filling factor.
