| Popis: | Optical phenomena in GaAs/AlGaAs quantum well nanostructures doped with acceptors were studied in the mid-IR spectral range. Equilibrium abso rption spectra were measured in a wide temperature range. Modulation of absorption in the presence of a strong electric field was studied. Absorption spectra revealed features that can be attributed to the resonance states of the acceptors. |
