Add/remove layers on either side of the barriers

It would be great if there was a capability to change the structure a little by adding a layer of N-/N+ GaAs on either side of the barriers, to make it a bit asymmetric. In other words, right now the tool does GaAs contact; N- GaAs; AlGaAs barrier; N- GaAs well; AlGaAs barrier; N- GaAs; N+ GaAs contact, if one could add a layer of N+ GaAs on the right side such that the structure is now GaAs contact; N- GaAs; AlGaAs barrier; N- GaAs well; AlGaAs barrier; N- GaAs; N+ GaAs “spacer”; N+ GaAs contact. It would be instructive to see what happens in such an asymmetric doping case.

Thanks a lot. It’s a great tool. Tanuj
