NanoTCAD ViDES is a device simulator able to compute transport in nanoscale devices, solving self-consistently the 3D Poisson and quantum transport equation within the NEGF formalism.

This version of NanoTCAD ViDES deals with Carbon Nanotube Field-Effect Transistors and Silicon Nanowire FET with arbitrary gate geometry. In particular, transport in CNT is computed solving the pz-orbital tight-binding Hamiltonian, both on a mode and real space basis set. Transport in SNWT is instead computed within the effective mass approximation.
