Influence of a natural superlattice from a surface with high indices on the spectrum of 2D electrons in a multivalley semiconductor
Volkov V.A., Sandomirskii V.B.
We consider the influence of a silicon surface with high indices on the spectrum of a two-dimensional {2D) electron gas in an inversion surface layer. Simultaneous allowance for the superperiod in the natural surface lattice and the multivalley character makes it possible to account quantitatively for the experimental data and predict new effects.
