- three different potential models:
- linear potential drop,
- semi-classical Thomas Fermi potential, and
- Hartree quantum charge-selfconsistent potential.
- relaxation in the reservoirs incorporated through a simple relaxation model.
- automatic determination of the AlGaAs barrier height.
- 2-barrier and multi-barrier devices.

- single effective mass model, no sophisticated multiband models;
- no transverse momentum integration;
- no exchange and correlation potential;
- GaAs / AlGaAs material system;
- no material parameters are exposed to the users for possible changes
Known issues with this release:
- transmission peaks may not be well resolved for thick barriers - observed for 7nm barriers.
- resonances are identified only by peaks in the transmission. There is no true spatial resolution and resonances in the triangular emitter well might be identified as central device resonance.
Speed-up of the code
- Certain portions of the Recursive Green Function previously written in MATLAB have been replaced with C code.
