The states density simulation in 2D-system of charged impurities

Condensed matter physics

The states in the upper Hubbard band in lightly doped quantum wells have been studied. To do this, the density of states of the valence-band was numerically simulated depending on the temperature for arbitrary parameters of the QW, using the Metropolis algorithm. The results were in qualitative agreement with the temperature dependence of photolumines-cence spectra and conductance in such structures.
