|Title:||The Fractional-dimensional Space Approach To Mbe-grown Quantum-sized Semiconductor Low-dimensional Systems|
De Dios-Leyva M.
|Abstract:||Shallow impurities and excitons in MBE-grown quantum-sized semiconductor low-dimensional systems are studied within the fractional-dimensional space approach. We present calculations for shallow-donor states in GaAs-(Ga,Al)As quantum wells and superlattices and for excitons in GaAs-(Ga,Al)As quantum wells and symmetric-coupled double quantum wells. Effects of growth-direction applied magnetic fields are also considered. Results are shown to be in good agreement with previous variational calculations and available experimental measurements. © 2001 Elsevier Science B.V.|
