Abstract :
We compare band-structure calculations obtained with modeling approaches hierarchically spanning from density functional theory to tight-binding, k·p and non-parabolic effective mass descriptions. We consider III-V quantum-wells with thickness ranging from 3nm to 10nm. Comparison with experiments for unstrained and strained InGaAs quantum-wells is also reported.
