Abstract:

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.
