A new version of NanoTCAD ViDES is available. This tool simulates nanodevices and materials at the atomic scale and using Non-Equilibrium Greens Functions (NEGF) to solve the Schroedinger's wave equations. There are modules to to help simulated carbon nanotubes, graphene nanoribbons, 2D graphene FETs, and 2D bilayer graphene FETs. A module for zincblend crystals for materials like silicon, germanium, and III-V is now being develop and should be available soon. The simulator is open source and uses the Python scripting language to define models. In his blog, Professor Giuseppe Iannaccone describes the tool and some of its features.
