pyQW

pyQW is a python script for calculating the properties of a finite quantum well such as those made from GaAs/AlGaAs. It uses an analytical model so it is not very extensible but it makes accurate plots of simple quantum wells and their wavefunctions. There is also a pdf which documents the theory used.

pyQW will calculate

• the energy levels for a simple potential well
• the Fermi level for a given doping and temperature
• the dipole matrix elements of the transitions
• the effective length of the transitions
• the plasma frequency and transition frequencies of the transitions

It doesn't

• calculate the effect of non-parabolicity or use advanced k.p models
• calculate the effect of the charges on the bandstructure (Poisson effects).
• include the effects of strain.
• calculate the effect of the interactions between the different transitions.
