- Title
Near-field effect in the absorption spectrum of impurities in crystals.
- Authors
Aleshkin, V.; Gavrilenko, L.
- Abstract
The effect of the near-field interaction of shallow donors in GaAs on the intracenter absorption spectrum of impurities has been considered. It has been shown that the near-field interaction leads to broadening of the absorption line, which increases with the donor density. The absorption line shape is no longer Lorentzian: its low-frequency wing becomes more prolonged than the high-frequency wing.
