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,

John
