The nextnano tools
We essentially offer five tools:
  • nextnanomat
    The graphical user interface for the nextnano≥, nextnano++ and nextnano.MSB software.
  • nextnano software
    Our Schrödinger-Poisson-Current solver written in Fortran.
  • nextnano++ software
    Our Schrödinger-Poisson-Current solver written in C++.
  • nextnano.QCL software
    Our NEGF code for quantum cascade lasers (QCLs) written by Thomas Grange based on the nonequilibrium Green's function method (NEGF).
  • nextnano.MSB software
    Our NEGF code for quantum cascade lasers (QCLs) and resonant tunneling diodes (RTDs) based on the multi-scattering Büttiker probe model (MSB).

Whether you want to use nextnano≥ or nextnano++ is up to you. Choose your flavor!

next generation 3D nano device simulator

nextnano≥ code logo

The nextnano≥ and nextnano++ software are simulators for calculating, in a consistent manner, the realistic electronic structure of three-dimensional heterostructure quantum devices under bias and its current density close to equilibrium. The electronic structure is calculated fully quantum mechanically, whereas the current is determined by employing a semiclassical concept of local Fermi levels that are calculated self-consistently.

Simulating quantum dots, quantum wires, RTDs, MOSFETs, HEMTs, etc.

  • includes group IV materials (Si, Ge, SiGe), all III-V and II-VI materials and its ternaries as well as lattice-matched quaternaries; the nitrides and the II-VI materials are available in the zincblende and wurtzite crystal structure
  • flexible structures and geometries (1D, 2D and 3D)
  • fully quantum mechanically, based on the 8-band k.p model within a finite differences grid
  • includes strain, piezo and pyroelectric charges
  • growth directions along [001], [011], [111], [211], ... in short along any crystallographic direction
  • equilibrium and non-equilibrium, calculation of current close to equilibrium (semi-classical), ballistic transport
  • magnetic field
  • optical absorption
  • BIO-nextnano
    Semiconductors connected to an electrolyte solution (Poisson-Boltzmann equation)
