文摘
- •
We calculate absorption coefficients of delta-doped QWs.
- •
Energy structure of delta-doped inside well QWs was calculated self-consistently.
- •
Variety of parameters has been studied.
- •
Impurity ionization has a strong effect on energy level mutual positions.
- •
The effects studied can be used to engineer tunable THz optical devices.
