摘要
Negative-donor (D- center) cyclotron resonance is studied in GaAs quantum wells of different widths to obtain information about the well-width dependence of the D- ground-state binding energy and optical transition energies in the range of 58-373 angstrom. The experimental magneto-optical transition energy is shown to increase with decreasing well width, in good agreement with variational quantum Monte Carlo results.
