Main Question or Discussion Point

Hi,

Really having a hard time finding conduction band offsets for semiconducting quantum wells - specifically GaAs/AlGaAs and CdTe/CdMgTe. I've heard 0.1 and 0.3 eV for AlGaAs and haven't seen anything on CdTe. Does anybody know of a reference where I could find these tabulated.
Thanks a lot.

btw. by offsets I mean the potential barrier height of the well - i.e. finite square well potential

If memory serves me correctly, the band offset for the GaAs/AlGaAs is a 60/40 split of the energy gap. Not too sure about the other system, in addition, I am not sure if CdTe/CdMgTe is type I or II.

I'd check Cardona and Yu and see where they lead you.
