Al mole fraction control

This tool could be made a lot more useful if the Al mole fraction ‘x’ could be controlled since that is one of the main ways in actual GaAs/AlGaAs heterostructure growth of controlling the electron/hole density. Also, there is a cross-over in mole fraction between a direct and indirect band gap with a corresponding change in the electron effective mass which of course affects real devices a great deal.
