Is there a self-consistent schrodinger-poisson solver on nanohub?

I’m new to nanohub, and I’m looking for a self-consistent schrodinger-poisson solver that can simulate GaAs/AlGaAs heterostructures (both n and p type). I found two programs, but neither seems to be particularly helpful – band structure lab is only for bulk crystals and nanowires, and the 1D heterostructure simulator I found is only for n-type systems, and it does not seem to do very fine calculations (i.e. I couldn’t get it to show the band bending necessary to create a triangular well in a single-interface GaAs/AlGaAs heterostructure). I’m essentially looking for an alternative to the Schrodinger-Poisson solver put out by Professor Snider at Notre Dame which has given me somewhat inconsistent results and doesn’t have any built in visualization capabilities. Anyone have any suggestions? Thanks,
